Error codes

Code	Description
500	All requests have failed due to errors. Invalid or unsupported inputs passed.
1003	External ID validation failed. The external ID does not meet the configured length requirements. Ensure the external ID length is between the minimum and maximum length configured for your organization.
1006	Mobile number validation failed. The mobile number does not match the expected format or required configuration is missing for the country.
1007	Error in customer registration: No Valid Mobile Number or External ID or Email provided required for registration. No valid mobile number, external ID, or email provided.
1043	External ID is required. This error occurs when your organization has configured external ID as a mandatory identifier but no external ID was provided.
8014	Mobile number validation failed due to missing or invalid country configuration. This occurs if the organization's base country is not set or if required country fields are missing.

External ID validation

The API validates the external_id field based on your organization's configuration settings. Understanding these validation rules helps prevent registration errors.

Validation rules

The external ID is validated against the following organization-level configurations:

Configuration	Description
`CONF_CLIENT_EXTERNAL_ID_MIN_LENGTH`	Minimum required length for the external ID. Default is 0 (no minimum).
`CONF_CLIENT_EXTERNAL_ID_MAX_LENGTH`	Maximum allowed length for the external ID. Default is 0 (no validation).
`CONF_USERS_IS_EXTERNAL_ID_REQUIRED`	When enabled, external ID becomes a mandatory identifier for registration.

How validation works

If CONF_CLIENT_EXTERNAL_ID_MAX_LENGTH is set to 0, length validation is skipped.
If both min and max length are configured, the external ID must have a character count between these values (inclusive).
Empty or null external IDs pass validation unless CONF_USERS_IS_EXTERNAL_ID_REQUIRED is enabled.
The maximum absolute length for an external ID is 250 characters.

Example

If your organization has configured:

CONF_CLIENT_EXTERNAL_ID_MIN_LENGTH = 8
CONF_CLIENT_EXTERNAL_ID_MAX_LENGTH = 12

Then:

"ABC123" (6 characters) → Invalid (error code 1003)
"ABC12345" (8 characters) → Valid
"ABC123456789" (12 characters) → Valid
"ABC1234567890" (13 characters) → Invalid (error code 1003)

Configuration
To configure external ID validation settings for your organization, contact Capillary support.

Additional notes

API behavior

If CONFIG_SKIP_SECONDARY_ID_ON_PRIMARY_MISMATCH is enabled, if the primary identifier is different but any of the secondary identifiers exist, a new customer is registered with the primary identifier ignoring the secondary identifier. The config is available on the Registration Page of InTouch Profile > Organization Settings > Miscellaneous.
Also, this config overrides CONF_PRIMARY_IDENTIFIER_STRICT_CHECK.

Auto-generation of external ID must be explicitly enabled if required by your registration process.
