What are Meta events (Conversions API) for chats?

30 Oct 2026 3 min read বাংলায় পড়ুন

Meta events send Meta a short note when something good happens in a chat: an order made from the chat is a Purchase, and a phone number the customer writes is a LeadSubmitted. Meta then learns which ads bring buyers, not only people who message.

Where to find it

Admin › CRM › Inbox › Replies & automations, then the Meta events tab. You need Inbox settings to open it.

How it works

  1. Switch it on. Tick Send events from chats to Meta.
  2. Your dataset. Write your Dataset (pixel) id from Meta's Events Manager (Datasets).
  3. Your token. Paste an Access token for that dataset. It is kept encrypted. Leave the box empty later to keep the saved one.
  4. Test code (optional). While testing, write the Test event code from Events Manager, so the events show in its test view. Clear it when you are done.
  5. Press Save. The heading says ● working when all three (switch, dataset, token) are set.

From then on:

  • Purchase: when someone makes an order from a chat, a Purchase goes to Meta with the order amount.
  • LeadSubmitted: the first time a customer writes a phone number in a chat, a LeadSubmitted goes to Meta.

Example: a customer clicks a Messenger ad of Rangdhanu Fashion and writes "01XXXXXXXXX". Meta gets a LeadSubmitted. The seller then makes a ৳2,450 order from the chat, and Meta gets a Purchase of ৳2,450.

Good to know

  • Each store uses its own dataset and token. Nothing is borrowed from the platform or from your website's pixel settings.
  • Connect the page in Events Manager. Your Facebook page (and WhatsApp account) must be connected to the same dataset there.
  • Who can be matched. Messenger and Instagram chats can always be matched. WhatsApp chats only when they came from a click-to-WhatsApp ad and the WhatsApp Business Account id is set. Others show as Cannot be matched.
  • Phone numbers are not sent as they are. They are scrambled (hashed) before they go to Meta.
  • Post comments do not send events.
  • Only from the day you switch it on. Orders and numbers from before that are not sent later.
  • Sent a few at a time, about every minute. If Meta does not accept one, it is tried again, up to 5 times. Then it shows as Failed.
  • The list shows every event with its status: Waiting, Sent, Failed or Cannot be matched, and the reason. Press Send now to try a waiting or failed one at once.

Common problems

  • The heading says ● off. The switch, the dataset id or the token is missing. Fill all three and save.
  • Many Failed events. Read the reason in the list. Often the token has expired or belongs to another dataset. Paste a new token, then press Send now.
  • WhatsApp events show "Cannot be matched". Those chats did not come from a click-to-WhatsApp ad, or the WhatsApp Business Account id is missing.
