How to get your Afterpay login details
To connect Afterpay to Synder, you need:
- Merchant ID
- Secret Key
Step 1: Get your Merchant ID
- Log in to your Afterpay merchant account.
- Open the Home page.
- Copy the Merchant ID from the footer below the Orders list.
Step 2: Get your Secret Key
The Secret Key is used to authorize the connection with Synder. Unlike the Merchant ID, this credential is not available inside the Afterpay dashboard. However, it’s always sent as an email when the Afterpay account is initially created.
- Search your inbox for an email from Afterpay sent to the email linked to your merchant account.
- Copy the Secret Key from that email.
If you can’t find your Secret Key in your inbox:
- Contact your Afterpay Business Development Manager, or
- Reach out to Afterpay Merchant Support and request your Secret Key
Important: Treat the Secret Key like a password. Do not share it publicly.
Step 3. Enter credentials in Synder
After you add the credentials to the correct fields on the Synder onboarding page, you will successfully establish the connection
