Subscription management

The Subscription Management section lets you configure webhook endpoints to receive real-time notifications about events in your Cobre account. When a payment completes, a balance changes, or a bulk file finishes processing, Cobre sends the details directly to your systems—no polling required.
This keeps your internal tools in sync, enables automated workflows, and gives your team instant visibility into treasury operations.

Accessing Subscriptions#

Navigate to Developers > Webhooks in the sidebar. You'll see the Subscriptions table showing all your active webhook configurations.

Viewing Your Subscriptions#

The Subscriptions table displays:
ColumnDescription
URLThe endpoint where Cobre sends notifications
DescriptionYour label for identifying this subscription
IDSystem identifier (format: sub_XXXXXX)
EventsHow many event types this subscription monitors
Creation dateWhen the subscription was created
The table shows pagination info (e.g., "1-5 of 5") when you have multiple subscriptions.

Creating a Subscription#

Click + Create subscription in the top-right corner to open the creation form.

Required Fields#

Webhook URL: The HTTPS endpoint that will receive notifications. This must be a publicly accessible URL that your server controls.
Events: Select which event types you want to monitor. You can choose multiple events for a single subscription—for example, subscribing to all money movement status changes with one endpoint.

Optional Fields#

Description: A friendly name to help you identify the subscription later. Examples: "ERP Integration," "Payment Alerts," "Accounting Sync."
Secret Key: A passphrase (10-64 characters) used to sign notifications. When provided, Cobre includes a cryptographic signature with each webhook so you can verify authenticity. Store this key securely—you'll need it to validate incoming requests.
After completing the form, click Create. Your subscription appears in the table immediately and begins receiving events.

Deleting a Subscription#

Hover over any subscription row to reveal the delete action. Deleting a subscription stops all notifications to that endpoint immediately.
If you need to change events or the URL, delete the existing subscription and create a new one with the updated configuration.

Webhook Security#

Signature Verification#

When you include a secret key during creation, every notification includes two headers:
HeaderContent
event-timestampUTC timestamp of event creation
event-signature64-character SHA256 HMAC hash
To verify a notification:
1.
Concatenate the timestamp and raw body: {event-timestamp}.{body}
2.
Calculate HMAC-SHA256 using your secret key (UTF-8 encoding)
3.
Compare your result to the event-signature header
Matching signatures confirm the notification is legitimate.

Delivery Retries#

Cobre retries failed deliveries automatically:
AttemptDelay
1st retry200ms
2nd retry400ms
3rd retry1000ms
Retries only apply to connection errors. If your endpoint returns a 4xx status, Cobre does not retry—so always return 2xx for successful receipt.

Best Practices#

Use HTTPS endpoints. HTTP is not supported. Ensure your webhook URL uses encrypted transmission.
Return 2xx quickly. Acknowledge receipt immediately, then process the event asynchronously. Long processing times risk timeouts.
Implement idempotency. Use the event id to handle potential duplicate deliveries gracefully.
Secure your secret key. Treat it like a password. If compromised, delete the subscription and create a new one.
Subscribe selectively. Start with only the events you need. You can always create additional subscriptions later.

Troubleshooting#

Not receiving notifications? Verify your endpoint is publicly accessible, uses HTTPS, and returns a 2xx response.
Signature mismatch? Check that you're using the raw body (no reformatting), correct concatenation order, and UTF-8 encoding.
Missing events? Confirm the subscription includes the event types you expect. Check the Events column in the table.
