List an advertiser’s Meta Pixels

Available on:

Live read. Asks Meta now for the Meta Pixels of one ad account. An ad set that optimizes for a conversion names one: send its id as pixelId when you create an ad set.

lastFiredTime tells which Pixel receives events. A Pixel that never received an event is usually not installed. When no page holds a Pixel, up to the page with no nextCursor, the ad account has no Pixel.

An advertiser that your organization does not own answers 404, with error of not_found. An advertiser that does not exist, and one that is not a Meta ad account, answer the same.

AdCrunch stores nothing from this read. Each request counts against the rate limits of Meta.

limit and cursor page the answer. Send nextCursor back as cursor to get the next page. A page can hold no row and still carry nextCursor.

400

The request does not match the schema of this operation: a field is missing or has the wrong type, or the body is not valid JSON. error is invalid_request, and issues names each field. Nothing was changed. Or AdCrunch cannot use the cursor: it cannot read it, or the cursor belongs to a different query. Then error is invalid_cursor. Send the nextCursor of the previous page with no change, or omit cursor to get the first page.
