Webhooks

Settings

You can enable Webhooks on TalkPlus Dashboard as follows:

• Enable Webhook feature

• Enter webhook handler endpoint

• Select events that will trigger webhook

Endpoint

• Endpoint must be able to handle HTTP POST request

• Endpoint must be able to handle JSON format

If endpoint fails to respond, TalkPlus will re-attempt once after 5 seconds..

Header

TalkPlus HTTP POST webhook will contain the following headers:

User-Agent	TalkPlus
content-type	application/json
x-talkplus-signature	payload is signed with your app API key using SHA-256 and then encoded to Base64

Verification

To Verify that the request to your endpoint came from TalkPlus server, compare x-talkplus-signature header value against the hash of response body.

Go

responseBody := "{\"event\":\"channel_added\",\"appId\":\"34f633c9-b012-4ca9-b453-2a4a460f464a\",\"channel\":{\"id\":\"webhook_test\",\"name\":\"webhook_test\",\"imageUrl\":\"\",\"data\":{\"test\":\"1\"},\"ownerId\":\"test1\",\"type\":\"public\",\"category\":\"categoryA\",\"subcategory\":\"subcategoryB\",\"privateTag\":\"\",\"invitationCode\":\"\",\"isFrozen\":false,\"memberCount\":1,\"maxMemberCount\":100,\"hideMessagesBeforeJoin\":false,\"members\":[{\"id\":\"test1\",\"username\":\"test1\",\"profileImageUrl\":\"\",\"disablePushNotification\":false,\"data\":{\"test\":\"1\"},\"updatedAt\":1699606163973,\"createdAt\":1697797296688,\"memberInfo\":{},\"lastReadAt\":0,\"lastSentAt\":0}],\"bannedUsers\":[],\"lastSentAt\":1699606164578,\"updatedAt\":0,\"createdAt\":1699606164578,\"mutedUsers\":[],\"pushNotificationDisabled\":false,\"pushNotificationSoundAOS\":\"\",\"pushNotificationSoundIOS\":\"\",\"privateData\":null,\"unreadCount\":0,\"lastReadAt\":0,\"lastMessage\":null}}"
