General setup (all card networks)

1. Let Pismo know the card network you’ll be using and request access to the Dispute API in EXT (test environment). To do this, go to the Pismo Service Desk, select Settings then, from the drop-down menu, select Disputes Configuration.
2. Contact your card network account manager and inform them that Pismo will process your disputes on their network.
3. Submit forms to the card network to request access to Disputes UI, API key, and certificates.

Visa setup

1. Go to Visa online
2. Create a Persona ID with Visa for both sandbox and production environments. Reach out to your Visa account manager
3. Send the Persona IDs to your Pismo account manager.

Pismo will open a request with Visa to link the Issuer's persona ID to Pismo's persona ID.

After Visa confirms the linkage, Pismo can perform Visa dispute API calls on an issuer's behalf.

Mastercard setup

1. Go to Mastercard connect
2. Create a project in Mastercard Developers for the Mastercom application.
3. Generate sandbox and/or production credentials within the project.
4. Choose one of the following options:
   • Option A: Create the credentials and securely share them with Pismo.
   • Option B: Grant access to Pismo's security team so they can create and manage the credentials for you. Once the credentials are validated, Pismo can perform Mastercard dispute API calls on an issuer's behalf.

Once the credentials are validated, Pismo can perform Mastercard dispute API calls on an issuer's behalf.
