Problem

The docker_compose.toml file is missing the following required block:

[payment_link]
sdk_url = "http://localhost:9050/HyperLoader.js"

Without this config, when generating payment links the SDK tries to fetch from https://beta.hyperswitch.io instead of the locally running backend. This results in failed payment_methods calls and the payment link not loading correctly for users.

Solution

Add the missing [payment_link] block to docker_compose.toml with the correct sdk_url pointing to the local service (http://localhost:9050/HyperLoader.js).

Expected Outcome

• Payment links generated locally should correctly load the SDK from the configured local URL.
• The payment_methods call should hit the backend specified in the hyperswitch-web service config instead of https://beta.hyperswitch.io.
• Users should be able to open a generated payment link and see it working without SDK load failures.

Files to Modify

• config/docker_compose.toml

Verification

1. Run docker compose up
2. Generate a payment link with:

   curl --location 'http://localhost:8081/payments' \
     --header 'Content-Type: application/json' \
     --header 'api-key: snd_5jYonmRK338pDuk1FqxSYfpPNutQUuVFEVV23qzpqzbQ4DYfbksIgdwIkgjb3vnP' \
     --data '{
         "amount": 100,
         "currency": "USD",
         "payment_link": true,
         "profile_id": "pro_ARVaflLlXRmGS5i8jfq5",
         "return_url": "http://www.google.com"
     }'

3. Open the generated payment link in a browser
4. Confirm that the SDK loads successfully and the payment_methods API call hits the local backend
