Send HTTP POST Request
blink:post?
This client action allows you to send a post request to the connector proxy url for your integration. It is a powerful client action as it allows buttons on cards to perform arbitrary actions in your integration.
| Field | Description | Required |
|---|---|---|
| url | URL encoded Base64 Encoded URL. This is just the path and will be prefixed by the app with https://api.joinblink.com. For example to forward a request to your integration code at /perform-action for your integration with id l- b2d471a5-5c7a-4268-bf61-708a48c60819, you would send the string /connector/l- b2d471a5-5c7a-4268-bf61-708a48c60819/perform-action base64 encoded as the value for url in this client action. | Yes |
| body | URL encoded Base64 Encoded JSON body. | Yes If you don't need to send a body just send e30%3D which when url decoded and then base64 decoded is an empty JSON object {} |
Example
This example posts the JSON {"test":"body"} to https://api.joinblink.com/connector/l-a26dab83-33a1-459b-adab-8333a1259b7d/test
