# Conversation API Postman collection

To view and copy Conversation API's Postman collection as a JSON file, [click this link](/assets/conversation_api_postman.353d8788ce22a1df1f34f6cefac8fe24758058bb579bd135ea6259ab3438707a.41cc2133.json).

After importing the collection, fill in the following variables:

| Variable | Value |
|  --- | --- |
| PROJECT | Your PROJECT ID |
| APP | Your app ID |
| CLIENT_ID | Your CLIENT_ID |
| CLIENT_SECRET | Your client secret |


For testing purposes, fill the WEBHOOK_URL by visiting [https://webhook.site/](https://webhook.site/) and use the generated link - the one under the **Your unique URL** label.

Caution:
The [https://webhook.site/](https://webhook.site/) URL given above should only be used for testing purposes. Using the Conversation API can generate high volumes of callbacks, which can easily exceed the TPS limits of certain webhook services. Additionally, sensitive information may be included in the callback, including message content and contact information. Ensure that you use a scalable and secure callback/webhook processor after your initial testing is complete.

Values for other variables can be obtained by calling corresponding requests:

- CONTACT - ID of contact created by calling **Create contact** request.
- WEBHOOK_ID - ID of webhook created by calling **Create webhook** request.
- CONVERSATION - a Conversation is created automatically when sending a new message. For example, with a Text Message request, send a message, then call [List conversations](https://developers.sinch.com/reference#conversation_listconversations) to get the ID of the conversation for this variable.
