This page(s) are optional and have to be provided by the integration layer when required. To use such custom pages before sending, the URI has to be configured as "BeforeSendRedirectUri" in the organization settings.

Typical scenarios:

• Ask for an Authentication, to get a bearer token which is later-on required for an integration listening on webhooks ("Callback Handlers")
• Validation of Envelope Parameters, showing a validation error when the envelope violates some company-internal rules (in case the business rules require to implement checks not supported by eSignAnyWhere out-of-the-box)
• Collect tagging data for the document(s), e.g. for a DMS/ECM/LTA integration.
