GetCustomerByID
CRM service 1.4: Returns one customer, identified by its integer ID, optionally with its custom fields and external keys.
| Service | CRM 1.4 |
| Endpoint | POST https://app{server-number}.timelog.com/{account}/WebServices/CRM/V1_4/CRMServiceSecure.svc |
| SOAPAction | http://api.timelog.com/services/crm/1_4/ICRMService/GetCustomerByID |
| Content-Type | text/xml; charset=utf-8 |
| Authentication | A token from GetToken |
| Changes data | No |
| Safe to retry | Yes |
How it works
Reads a single customer by the customer's integer ID. The customer comes back as Return[0] of the Response envelope. Set loadCustomFields / loadExternalKeys to also fill the customer's custom fields and external-system keys; otherwise those lists are empty and IsCustomFieldsLoaded / IsExternalKeysLoaded are false. An unknown ID is an ERROR, not an empty result: ResponseState Error, ErrorCode 40001 and a data-layer message.
Parameters
Each parameter has one label: Required, Conditional (required depending on other values) or Optional. Send them in the order shown.
Integer ID of the customer.
Optional. Default false. true = fill CustomFields and set IsCustomFieldsLoaded.
Optional. Default false. true = fill ExternalKeys and set IsExternalKeysLoaded.
The token from GetToken: Initials, Expires and Hash, sent back unchanged.

{…} placeholder with your own value.Response
The call returns the standard response envelope. Check ResponseState first: a failed call still returns HTTP 200.
Success, Invalid or Error.
0 on success, otherwise the error code. See Errors.
Response<Customer>: Return holds exactly one Customer. No 'Successfully called' message is added; Messages holds only the call duration. Never empty on success: an unknown ID is ResponseState Error.
Example response
HTTP/1.1 200 OK

Request block is shortened.Errors
All errors come back with HTTP 200: check ResponseState, ErrorCode and Messages. The errors every operation can return (expired or invalid token, API not enabled, HTTPS required, general errors) are listed once in Responses and errors.
Errors specific to this operation:
| ResponseState | ErrorCode | Message | What it means | What to do |
|---|---|---|---|---|
| Error | 40001 | Error during call on TimeLog.API, Message 'Unable to retrieve result from … with ID {id}' | No customer has this ID. | Check the ID; treat this message as 'not found'. |
