Step 1: Confirm support for the connectivity and idempotency requirements
It is important to understand and ensure you are able to support the transport layer and application layer security requirements as well as the protocol standards, notably those related to idempotency, prior to integrating.
Step 2: Work with Google to set up your vendor configuration
Google needs to configure the host(s) and PGP keys to establish communication with the vendor hosted APIs you implement.
First, you will need to determine the URL for the host(s) on your side responsible for serving the vendor hosted APIs. If your implementation is split across multiple hosts (e.g. a 3rd party core or other service provider), indicate which endpoints are served directly by you and which are handled on your behalf by a service provider.
Next, if you are hosting any of the vendor hosted APIs, you will need to generate the PGP keys that should be used for application layer encryption with your endpoints.
To initiate the vendor configuration and key exchange process, provide the following to your Google technical point of contact:
- The hostname for the server(s) responsible for serving the vendor hosted APIs.
- the subpath to your API implementation
- The public portion of the PGP key pair you generated
Once Google has set up your vendor configuration, Google will reply with your Payment Integrator Account ID (PIAID) and Google's public PGP key specific to the endpoints you are hosting.
Step 3: Establish sandbox echo connectivity
Once you have verified you can meet the integration requirements, have your PGP
keys, and have a Payment Integrator Account ID (PIAID)
from Google, you are ready to implement and test the Google hosted
echo endpoints. Refer to
echo definitions in the API docs for
the service you are implementing under
These scripts use the Google-hosted Sandbox environment echo method to test baseline connectivity:
Step 4: Integrate with the APIs
Once you have the
echo endpoints working in sandbox, you're ready to
integrate with the rest of our APIs.
Refer to to API docs for the services you are implementing under Reference.
Step 5: Upload your company logos
Follow the Logo branding guidelines.
Step 6: Testing
During development, you can use our hosted Amplecash service to mock requests and responses. Once your solution is ready to test a flow end to end, your Google technical contact can help you perform live tests from our sandbox environment.
As development wraps up follow the testing process to prepare for launch.
Step 7: Launch!
Follow the launch process to ensure as smooth a release as possible.
