There are several possible issues that may prevent a donation from processing in your LCRM. These are:
  •  Are the Campaign and donation form in LO cross-referenced to the same campaign in CRM? Don't forget to set the designation field when cross-referencing to process recurring gift donations? (Alternatively, see: Process credit cards through Luminate CRM with no cross-references)
  •  Are the API Permissions set in the API Admin group? Check these settings:
    • Support Management > Force API
    • Offline Donation API > Add and Refund offline donations via API
    • Recurring Gifts > Recurring API
  • Is the donation form published?
  • Does the donation form allow offline donations?
