Common questions and solutions for acceptor boarding issues.

### Application creation

<AccordionGroup>
  <Accordion title="I called createAcceptorApplication, but I'm not sure what's required to proceed.">
    * Ensure all mandatory fields (e.g., businessName, etc.) were included.
    * Check for missing required fields using validation errors returned in submitAcceptorApplication.
  </Accordion>
</AccordionGroup>

### Stakeholder management

<AccordionGroup>
  <Accordion title="I'm not sure whether to use updateAcceptorApplication or createAcceptorApplication to add a stakeholder.">
    * Use updateAcceptorApplication if you have already create the application.
    * Use createAcceptorApplication if you are creating the application for the first time.
  </Accordion>

  <Accordion title="Why are my updates to a stakeholder not being saved?">
    * Make sure you're referencing the correct stakeholder ID.
    * Ensure updateAcceptorApplication is using the updateBusinessStakeholderInput or updatePersonStakeholderInput.
    * Confirm that the stakeholder was not unintentionally removed in another request.
  </Accordion>

  <Accordion title="I added a stakeholder, but validation is failing. Why?">
    * Check that all required fields for that stakeholder type (e.g., DOB, SSN, title) are provided.
    * Ensure address formats and country codes conform to ISO standards (e.g., `US`, `CA`).
  </Accordion>

  <Accordion title="Can one person or company be assigned multiple types (e.g., owner and control person)?">
    * Yes — use the roles field to specify multiple applicable types when adding the stakeholder.
    * Ensure the same stakeholder isn't duplicated; instead, reuse the stakeholder with different types.
  </Accordion>
