WhatsApp 云 API 在我的 webhook 上多次发送旧消息入站通知

Question

I'm new in using WhatsApp cloud API, I've set up one webhook with my WhatsApp cloud API.but the problem is that after some time it sends an inbound notification of an old message again to my webhook.

Answer 1

It is called an Idempotence problem. Here's what I've done to avoid it.

1. Store each payload in a database when your webhook gets hit.
2. Before processing your logic, check whether or not the current payload is already received.
3. Delete more than three days old records from your database.

Answer 2

If a notification isn't delivered for any reason or if the webhook request returns a HTTP status code other than 200, we retry delivery. We continue retrying delivery with increasing delays up to a certain timeout (typically 24 hours, though this may vary), or until the delivery succeeds.

I will share my experience and maybe it can help some of you.

I was returning the status code 200 from my server . But W hatsapp Api Cloud still returned 15 notifications per message .

the problem was that in the past, maybe one month before. I had actived webhook messages notifications, but I didn't respond with the status 200 . meanwhile I was building the sending messages backend logic. so, there were thousands of webhooks no responded with the Status code 200. So my facebook app went crazy, and when I decided to respond with the status code 200. it didn't work.

the solution was to create another facebook app. and the webhooks worked well .

Answer 4

Had the same problem, tried to delete the app but didn't work, I was still receiving old messages from the old app.

TLDR; don't use the same test number with more than one Facebook App.

Even creating a new app, Phone Number ID and Account ID were still the same, my speculation is that the webhooks payloads are tied more to the test phone number rather than the Facebook App. For this reason, if you have another application with the same test number and a not working webhook, it keeps sending the same messages to both webhooks.

Within the POST defined in your Webhook, you should always return HTTP Status 200, check that this happens even within your Promises
