How to configure a SePay webhook
Content
Quick summary: To configure a SePay Webhook, follow 3 steps: Step 1 is to go to the Courses section of the system, turn on the feature, then create and copy the API Key and Webhook URL. Step 2 is to log in to SePay, open Webhook Integration and click to add a new webhook. Step 3 is to fill in the webhook name, choose the trigger condition for incoming money, pick the linked bank, paste the Webhook URL and API Key you copied, then save.
Step 1: Get the API Key and Webhook URL from the system
- Go to Courses section of the system.
- Turn on the status to activate the feature.
- Click Create Key so the system generates a random API Key.
- Copy API Key you just created.
- Copy Webhook URL (if you are using SePay).
Step 2: Configure the Webhook on SePay
- Log in to SePay.
- Go to Webhook Integration.
- Click the + Add Webhook button to create a new payment webhook.
Step 3: Set up the Webhook on SePay
- Enter a name cho Webhook.
- Select “Money received” option (the webhook fires when the account receives money).
- Select Linked bank where you want to receive money.
- Select “No” option in the transaction confirmation requirement.
- Paste Webhook URL you copied from Step 1 into the matching field.
- Select “Yes” option to activate the webhook.
- Select Option “API Key” to verify the transaction.
- Type API Key you copied from Step 1 into the input field.
- Activate the webhook by selecting “Activate”.
- Click Plus to save the configuration.
