Using Webhooks

Basic

You can configure your LeadPro account to send events to a designated endpoint when a lead is either created or updated. This is known as a 'webhook'.

To use the webhook functionality, you'll need to:

Create an endpoint to receive the data from LeadPro
Add the endpoint URL to the developers section of your dashboard

Once enabled, LeadPro will POST the event data to your endpoint as JSON. The payload contains two fields:

"event" – which can be either "lead.created" or "lead.updated"
"data" – which contains the lead data, and consists of the following fields:

Advanced

For additional security, you may wish to verify that the requests being made to your endpoint are coming from LeadPro. We include a JWT token in the "Authorization".

{
  alg: "HS256",
  typ: "JWT"
}

The body of this token contains the full payload, and we recommend using this instead of the actual payload.

The token signature is the base64 encoding of the HS256 encrypted header and body. The key for verifying this signature is generated in the developers section of your dashboard under the webhook signing secret.
