In order to use the web service interface to submit XML applications directly to Grants.gov, you must obtain a certificate and request for it to be installed on Grants.gov.
Obtain / Renew a Certificate
To renew or obtain a new certificate for the Grants.gov Production and Training environments:
Request Certification Installation at Grants.gov
Provide the Grants.gov PMO with the following information using the Certificate Request Form.
Submit this information by clicking the “Email Request” button in the form that will send the request to Grants.gov at email@example.com. Grants.gov will notify you via email once it has been installed.
Authorize the Certificate
After the certificate has been installed, the E-Biz Point of Contact (POC) must authorize the Applicant Status.
Using a S2S Service Provider
If you are using a grants application system provided by an S2S vendor, your service provider can supply a certificate for you. Otherwise, you may obtain your own certificate from a recognized certificate authority as specified above and give it to the Service Provider.
