Error Handling

Response Codes

If an API call is successful, it returns a “200 OK” response.  If there is an exception, an error code along with an exception message is returned. Here is the list of response codes and their meaning –

Response Code Description
200 OK This is the status code for successful API call. Check the message body to find JSON data if the API call is expected to return a result.
401 Unauthorized The API call was made with invalid access credentials. Check your accessKey and secretKey.
400 Bad Request The message body on the request is not as per API specification. Make sure that content type is set to “application/json” and the JSON body has correct attribute names and structure.
404 Not Found The API could not be found. Please check the API signature (syntax).
500 Internal Server Error The API called failed. There could be many reasons for it. Check the exception message to get more details.

 In the case of a 500 Internal Server Error, a JSON response body which will provide information about the error also appears.

Below is an example of an error when a mandatory parameter of an API call is not being passed.

  "ExceptionMessage":"'leadId' is mandatory for updating lead"

Logging API calls

We strongly recommend that you log all API calls and their results during while working on the integration with LeadSquared. Maintain a log file as part of your application and log the API signature (you may strip the API keys) along with any API URL parameters and request body (JSON). Log the API response code. In case of an error, log the JSON body of the error message. Once your integration is stable you can reduce the level of logging and log only API name (signature), response code and error message if any.

Note: We DO NOT keep logs of all the API calls within the LeadSquared platform logs. We log only important events (like platform exceptions). Therefore, we may not be able to tell you why a particular API call resulted in an error or behaved in unexpected manner unless you share your logs with us.


DateTime Format

Please note that the DateTime format for all date fields is “yyyy-MM-dd HH:mm:ss”.

  • The date should always be in UTC. You’ll have to convert the DateTime from your time-zone to UTC.
  • The time is in 24-hour format and there is a space between date and time.

For example,“2018-10-05 14:34:53” is a valid value that represents 5th Oct 2018, 2:34:53 PM in UTC.

Note: Date-time fields returned in the API response will contain milliseconds and have the format “yyyy-MM-dd HH:mm:ss.SSS”. However, the date-time format accepted for all input/update calls is “yyyy-MM-dd HH:mm:ss” (must not contain milliseconds).
