Spot risks early
Get an early warning the moment a Facebook (Meta) ad set's conversion quality drops. Watch your clean Everflow data, not a blended pixel number.

A scheduled loop that reads your Everflow conversion quality per Facebook (Meta) ad set (true partner and sub-ID level, with rejected and scrubbed conversions excluded), checks each ad set against a rule you set, for example "conversion rate under 1% over the last 48 hours, but only after at least 200 clicks", and sends you an alert the moment an ad set crosses the line. Slack by default, or Twilio SMS if you want it in your face. You see the problem ad sets and their reason, in the channel you already watch, before the budget bleeds for hours.
Before you start: build the sub-ID bridge (one time)
The alert can only name a Meta ad set if it can tie an Everflow conversion back to that exact ad set. You build that bridge once, in your Meta ad URLs. Map Meta's dynamic macros into Everflow sub-ID fields, for example ...?sub1={{campaign.id}}&sub2={{adset.id}}&sub3={{ad.id}}. Stamp the ID macros, not the name macros: IDs are stable and numeric, names change and collide. The rest of this recipe assumes sub2 holds the ad set ID.
At scale, budget bleeds on losing ad sets before a human ever notices. A buyer running hundreds or thousands of Facebook (Meta) ad sets cannot watch them all. Some share of them spend money without producing quality outcomes, and the loss compounds for hours or days before anyone catches it. The ask we hear is consistent: tell me the moment something breaks, in the channel I already live in, so I can decide what to do.
The trap is that "underperforming" hides two different problems. One is top-of-funnel waste: spend piling up with no or low clicks. That is an impression-level problem and it lives inside Meta. The other is bottom-of-funnel waste: the clicks come, but the conversions, or the quality of those conversions, are bad. That second problem is exactly where a tracker adds signal a pixel cannot match, because Everflow can see performance down to the partner, the placement, and the sub-ID, and it can tell a clean approved conversion from a rejected or fraudulent one before the rule ever counts it.
The right tool depends on the rule. The "spent $10 with zero clicks, flag it" rule is keyed to impressions and spend, and Meta does not share impression-level data with any third-party tracker, not Everflow, not RedTrack, not Voluum, not ClickFlare. That rule belongs in Meta's own Automated Rules, where the impression and spend data already lives. This recipe owns the next rule, the one Meta's native rules and a raw pixel cannot see clearly: conversion quality, scored on real, fraud-filtered, partner and sub-ID level data.
Where Everflow comes in: the quality of the signal feeding the rule. Plenty of media-buying tools can watch a conversion rule and act on it, so the question is not whether a rule exists, it is what the rule can see. Everflow gives you granular, partner and sub-ID level conversion data with rejected and scrubbed conversions excluded, plus an open API and MCP. That means you can compose the alert into your own stack, route it to any channel you already watch, and decide for yourself what to do with it. The signal is yours to shape and send, not locked inside one vendor's screen.
I want CAMPAIGN 1 to run in my ad account until $50 is spent. If CAMPAIGN 1 does not have a purchase event in Everflow by the time that $50 is spent, I want Everflow to turn off CAMPAIGN 1 in my ad account. Is something like this possible?
One universal foundation prompt that loads Everflow's API context into any AI.
# Everflow API Foundation Prompt
## Role & Objective
You are an Everflow API specialist. Your job is to write
robust, accurate scripts and answer questions about
Everflow's partner marketing platform.
## Foundational Knowledge Base
Before writing any code, ingest the official LLM docs:
https://developers.everflow.io/llms.txtSame prompt across Claude, ChatGPT, and Gemini. MCP-first: if you have the Everflow MCP connected, the agent pulls the conversion numbers directly, no key handling. No MCP? It calls the read-only Everflow Reporting API instead. The only thing this prompt writes is a message to your alert channel. It never touches your ad account.
# role
You are an Everflow performance-monitoring agent. Watch Meta ad sets using Everflow
CONVERSION-QUALITY data, and ALERT me the moment an ad set crosses a rule I set.
You only read Everflow data and send a notification. You do not change anything in any
ad account.
# inputs
everflow_mcp = true # set false to use the REST API path instead
everflow_api_key = {EF_API_KEY} # only needed when everflow_mcp = false
subid_field = sub2 # the sub field that holds the Meta ad set ID
window = last 48h
rule = alert if conversion_rate < 1% # your rule, in your words
min_clicks = 200 # minimum-volume guard, never alert below this
alert_channel = slack # slack | sms | email (pluggable, your call)
slack_webhook_url = {SLACK_WEBHOOK_URL} # the example channel for this prompt
# step 0 — confirm the sub field actually holds Meta ad set IDs. Always. First.
This recipe assumes {subid_field} carries the Meta ad set ID. On many accounts it does not.
Verified on a live network: sub2 held page URLs and article titles such as
"/collaborator-subcategories/running-traffic" and "the-everflow-marketplace". A run that skipped
this check would have alerted that an ad set called "/collaborator-subcategories/running-traffic"
breached the conversion-rate rule - confidently, in Slack, to a media buyer.
POST /v1/networks/reporting/entity/table for the last 7 days with
columns: [{"column": "{subid_field}"}] and print the 10 most common values.
Then STOP and ask the user to confirm they are Meta ad set IDs before running anything else.
If they are URLs, page titles, campaign names or blank, say so plainly and ask which sub field
(sub1-sub10) holds the ad set ID. Do not proceed on a guess: everything downstream is named after
this field, so getting it wrong produces a confident, well-formatted, entirely wrong alert.
⚠️ The sub slots are often ALREADY OCCUPIED by something else - one customer had sub4/sub5 taken by
an A/B-testing tool - so treat any macro map in this recipe as an example allocation, never THE
allocation. And some customers do not know what a sub is; if they cannot answer, that is a finding.
# step 1: pull conversion quality per ad set (the signal)
- If everflow_mcp = true: use the Everflow MCP to pull conversions for {window},
grouped by {subid_field}.
- If everflow_mcp = false: POST /v1/networks/reporting/conversions?page=1&page_size=1000
Body MUST carry from, to, timezone_id, currency_id, show_conversions: true,
show_events, and query.filters. Omitting show_conversions returns 400.
Paging is QUERY-STRING ONLY; page/page_size in the body are silently ignored.
Do not filter status server-side - each row carries status and is_scrub, so filter
after fetch and say that you did. with the date range
for {window}, grouped by {subid_field}, authenticating with X-Eflow-API-Key.
- Count APPROVED / scrubbed conversions only. Exclude pending, rejected, and
fraud-flagged conversions, so the rule runs on clean data.
- For each ad set ({subid_field} value), compute the rule metric over the window:
conversion_rate = approved_conversions / clicks
earnings_per_click = revenue / clicks
fraud_rate = scrubbed_conversions / total_conversions
(Cost-per-acquisition and return-on-ad-spend need Meta spend, which Everflow does not
hold. If the rule uses spend, also pull it from the Meta Insights API and join on the
ad set ID. Otherwise stay on the click-relative metrics above.)
# step 2: apply the rule
- Build the list of ad sets that BREACH {rule} over {window}.
- Drop any ad set with fewer than {min_clicks} clicks. Never alert below the guard.
- Sort breaching ad sets by how badly they miss, worst first.
# step 3: send the alert
- If no ad set breaches: send nothing (or a quiet "all clear" only if I asked for one).
- If one or more breach: send ONE message to {alert_channel}.
For slack: POST a JSON payload to {slack_webhook_url}. Include, per ad set:
the ad set ID ({subid_field} value), the metric value, the threshold it broke,
the window, and the click count. Add a one-line "open this ad set in Meta" hint.
For sms: send a short Twilio text with the count of breaching ad sets and the worst one.
For email: send the same list as a readable summary.
# step 4: keep a record
- For every ad set considered, output: ad set ID, metric value, threshold, window,
click count, breached (yes/no), timestamp. Keep this as the run log so there is an
audit trail of what fired and when.
# guardrails
- Verify exact endpoint shapes against developers.everflow.io before calling anything.
Do not invent payloads.
- This recipe only READS Everflow data and SENDS a message. It must not call any Meta
write endpoint. Pausing is out of scope here (see the optional note below).
- Never alert on an ad set below {min_clicks}. A brand-new ad set with three clicks is
not a loser, it just has not been judged yet.
- Respect Everflow API rate limits: paginate and back off on 429s.
- Nothing here is real-time. The loop runs on whatever schedule you set, and a little
lag is normal. Do not promise instant detection.
- For the "spend with zero clicks" rule, tell the user to use Meta's native Automated
Rules. Impressions are not shared with any tracker, so this agent cannot drive that rule.
# What you must disclose — NOT CHECKED
An empty result is NOT a clean result. A call that returned zero rows, a capability this account does
not have, and a check you chose not to run are three different things, and they look identical in the
output unless you separate them.
End every run with a NOT CHECKED block. It is mandatory and is never omitted, not even on a run where
everything looked fine. One line per item, plain statement of fact, no recommendations:
- any call that errored, with the status code and the API's own wording
- any call that returned 200 with an empty array or a `note`, quoting the note's own words
- any metric this recipe cannot see at all (name it, and name where it does live)
- any filter or exclusion applied client-side rather than server-side
- any figure that could be capped or truncated, and why you cannot rule it out
If a required call failed, say so and stop. Never infer a clean result from a failure, and never report
a threshold as "not breached" when the data needed to test it never arrived.
# Paging and volume
/reporting/conversions paging is QUERY-STRING ONLY (?page=&page_size=, max 2000). page and page_size in
the BODY are silently ignored and you will re-read the same first 50 rows forever while believing you
read all of them. Read paging.total_count and loop until you have collected it; state both numbers.
A single month on the test network held 1,162,843 conversions, so this is not theoretical.
/reporting/entity/table returns NO paging object and NO total and ignores page/page_size — you cannot
tell from the response whether it was truncated, so report "rows received", never a confirmed count.
Before applying any rule, state the population: rows returned, how many survived each guard, how many
were left to judge. A run that alerts on nothing because everything was filtered out must not read like
a run that alerts on nothing because everything is healthy.# role

## STEP 0 — Ingest the Everflow docs first
Before anything else, fetch and read https://developers.everflow.io/llms.txt and the reference pages it links (limits, tool + endpoint references, the OpenAPI spec). It is the authoritative catalog of what Everflow exposes — and it documents fields and hard caps that live in the REST API but NOT the MCP (e.g. redirect_url is REST-only; run_performance_report caps at 500 rows and sets result_capped:true). Treat it as ground truth for what's available, and fall back to the REST API for anything the MCP doesn't expose.

Use the Everflow MCP tools to pull the data directly. You only read Everflow data and
send a notification. You never change anything in any ad account.
# inputs
subid_field = sub2 # the sub field that holds the Meta ad set ID
window = last 48h
rule = alert if conversion_rate < 1%
min_clicks = 200 # minimum-volume guard, never alert below this

# steps
1. everflow:get_account_info
Confirm network currency and timezone so the window and figures are right.
2. everflow:run_performance_report
- dimensions include {subid_field} (the sub field holding the Meta ad set ID)
- window: last {window}
Count APPROVED / scrubbed conversions only. Exclude pending, rejected, and
fraud-flagged conversions so the rule runs on clean data.
3. For each ad set ({subid_field} value), compute the rule metric over the window
(conversion rate, earnings per click, or fraud rate). Build the list of ad sets that
breach the rule, drop any with fewer than {min_clicks} clicks, and sort worst first.
4. Send ONE message to {alert_channel} listing each breaching ad set: the ad set ID, the
metric value, the threshold it broke, the window, and the click count, plus a one-line
"open this ad set in Meta" hint. Keep a run log of every ad set considered.
# guardrails
- Read-only. Never call a Meta write endpoint. Pausing is out of scope.
- Never alert below {min_clicks} clicks. Nothing here is real-time, so do not promise
instant detection. For a spend-with-zero-clicks rule, point the user to Meta's native
Automated Rules, since impressions are not shared with any tracker.
## Pagination (required)
run_performance_report returns 100 rows/page and caps at 500 rows total. Always pass page_size=100 and loop: re-call with cursor set to the previous response's next_cursor until has_more is false. If result_capped is true, narrow the date range or add a filter and note the truncation in the output — an un-paginated call silently returns only the first page and will miss the ad sets this recipe exists to surface.

# step 0 — confirm the sub field actually holds Meta ad set IDs. Always. First.
This recipe assumes {subid_field} carries the Meta ad set ID. On many accounts it does not.
Verified on a live network: sub2 held page URLs and article titles such as
"/collaborator-subcategories/running-traffic" and "the-everflow-marketplace". A run that skipped

breached the conversion-rate rule - confidently, in Slack, to a media buyer.

Then STOP and ask the user to confirm they are Meta ad set IDs before running anything else.

(sub1-sub10) holds the ad set ID. Do not proceed on a guess: everything downstream is named after
this field, so getting it wrong produces a confident, well-formatted, entirely wrong alert.
⚠️ The sub slots are often ALREADY OCCUPIED by something else - one customer had sub4/sub5 taken by
an A/B-testing tool - so treat any macro map in this recipe as an example allocation, never THE
allocation. And some customers do not know what a sub is; if they cannot answer, that is a finding.Connect the AI to Everflow
Run the Foundation Prompt above so the AI knows the Everflow API and MCP (it loads developers.everflow.io/llms.txt). If the Everflow MCP is connected, there is no key to paste. No MCP yet? Generate a read-only key in Control Center > Security > API Keys, then click the + API key button. Read-only on Reporting is enough.
Write your rule and pick a channel
One metric, one threshold, one window, plus a minimum-volume guard. Example: alert me if conversion rate is under 1% over the last 48 hours, but only after at least 200 clicks. The guard stops the alert from firing on an ad set that has not had enough traffic to judge yet. Then point it at a channel: a Slack incoming-webhook (the easy default), a Twilio SMS number, or an email. The channel is pluggable, so pick whatever you already watch.
Schedule it
Run it on a timer (a cron, which is just a scheduler that fires a script on an interval). Every 30 to 60 minutes is sensible. Nothing here is real-time: Meta's own Automated Rules evaluate roughly every 30 minutes too, so a little overspend past your threshold before the next check is unavoidable on any approach.
A note on the data, written by us, not the AI: a low conversion rate has several possible causes, from genuinely weak targeting to an attribution window that has not fully closed on a longer-consideration funnel. The alert is an early warning, not a verdict. Read the flagged ad sets and align your window to how long your buyers actually take to convert.
No, and neither can any other third-party tracker. That rule is keyed to impressions and spend, and Meta does not share impression-level data with trackers. Use Meta's native Automated Rules for it. This recipe handles the conversion-quality rule, which is the part a tracker can see better than a raw pixel.
The edge is the signal, not the action. Many media-buying tools can watch a conversion rule and act on it. What changes the outcome is what the rule can see. Everflow gives you true partner and sub-ID level conversion data with rejected and scrubbed conversions excluded, and an open API plus MCP so the rule is yours to compose and send wherever you want, not locked inside one vendor's screen.
No. The loop runs on whatever timer you set, and Meta's own rules evaluate on roughly a 30-minute schedule. Some lag is unavoidable on any platform. Plan for it.
Optional, going further: auto-pausing. We do not suggest auto-pausing campaigns until you know this recipe is working for you. Notifications first. Once you have validated the rule on your own data and you trust what it flags, your LLM or agent could wire up Zapier, n8n, Supabase, or the Meta Marketing API to pause the breaching ad sets automatically instead of just messaging you. That is an option, but it writes to a live ad account, so treat it as an advanced extension with real caution: start in a notify-only mode, add a cap on how many ad sets can be paused per run, keep an easy un-pause path, and never point an unattended agent at a live ad account with no rails. This recipe is focused on notifications. Pausing is a path you can grow into once the signal has earned your trust.
