There could be a few different reasons why you are getting the Zoho 204 error:

Invalid API Request

This is the most common cause of the 204 error in Zoho. It occurs when the API request sent by the client is invalid or malformed. For example, you may be passing incorrect parameters or making a request to a non-existent API method. Double check that your API calls are formatted properly.

Authentication Issues

If there is an issue with your Zoho account authentication, it can also lead to 204 errors. Make sure you are using the correct auth tokens when making API requests. If your auth tokens have expired, regenerate them.

Access Restrictions

Certain access restrictions set in your Zoho account can cause a 204 error. For instance, if API access for your account is restricted to certain IP addresses, and you make requests from an unrecognized IP, it will result in a 204.

Server-Side Problems

In rare cases, there could be an issue with Zoho’s servers that is causing the 204. Usually, these are temporary glitches that get resolved quickly. Trying the request after some time could work.

5 Easy Steps to Fix Zoho 204 Error

Follow these troubleshooting tips to fix the 204 error in Zoho:

1. Double Check API Parameters

Carefully examine the parameters, headers, request body etc. passed in your API call. A simple spelling mistake could trigger an invalid request error. Refer to Zoho’s API docs for the right formats.

2. Use Proper Authentication

Make sure you are passing the auth token with the right scope for the resource you are trying to access. Also, regenerate your auth tokens if needed.

3. Check User Permissions

Confirm that the user making the API requests has the necessary permissions for the action. For example, deleting a record requires write access.

4. Retry Request Later

If it’s a temporary server issue, retry making the API call after some time. Even a simple retry can resolve transient glitches.

5. Contact Zoho Support

If the above steps don’t work, reach out to Zoho customer support with relevant API call details. They should be able to pinpoint and resolve the issue.

Tips to Avoid Zoho Error 204

Here are some best practices you can follow to avoid the 204 error when working with Zoho APIs:

  • Always refer to Zoho’s API documentation for syntax, parameters, headers etc. when making API calls.
  • Use POSTMAN or other API tools to validate your requests before adding them to your code.
  • Set proper user permissions in your Zoho account for the resources you need to access.
  • Handle auth token expiration gracefully by regenerating tokens when needed.
  • Add error handling in your code for cases when the API server is temporarily unavailable.
  • Enable logging of API requests & responses to troubleshoot issues easily.
  • Check for rate limiting headers in the response to avoid hitting request quotas.

By following these tips, you can proactively avoid API issues like the Zoho 204 error.

Why Does Zoho Return 204 Error Code?

The HTTP 204 status code that Zoho returns for some failed requests generally means No Content.

According to the HTTP specification, the 204 code indicates:

The server has successfully fulfilled the request and that there is no additional content to send in the response payload body.

In Zoho’s case, a 204 response simply means that the API request you made was valid, but no data or content was returned.

This could happen due to a variety of reasons:

  • The resource you requested via the API does not exist
  • The request filters you applied excluded all matching data
  • You lack access permissions to view the resource
  • There was a temporary server error while fetching the data

So in summary, the Zoho 204 error is the API’s way of telling you that your request was processed successfully, but intentionally no data was returned. The key is to analyze why no data was returned and fix that issue.

Common Zoho Resources that Return 204 Error

While the Zoho 204 No Content error can happen with any Zoho API, some commonly accessed Zoho resources are more prone to this issue under certain conditions. These include:


  • Fetching non-existent records
  • Getting records without sufficient access privileges
  • Applying restrictive filters that exclude all data

Zoho Books API

  • Requesting unauthorized reports
  • Accessing organizations as a regular user
  • Searching records outside company scope

Zoho Recruit API

  • Trying to view resume details without admin access
  • Retrieving inactive/closed jobs
  • Searching candidates with no match

Zoho Inventory API

  • Getting items or orders from unlinked organizations
  • Accessing invoices of other accounts
  • Lookup with invalid reference IDs

Zoho API for SalesIQ

  • Requesting visitor details without admin access
  • Using filters that exclude all visitors
  • Getting analytics outside date range

So when working with these APIs, be aware of scenarios where a 204 could occur and handle it properly in your code.


Q1. Why am I suddenly getting Zoho Error 204, even though my API calls were working earlier?
This could happen if your Zoho account permissions or API access settings were modified recently. Check if you still have required permissions.

Q2. How can I confirm that my Zoho API call is valid before deploying it to production?
Use the Postman tool or Zoho’s API console to test your actual API calls during development. This will reveal any errors or missing parameters.

Q3. I’m getting Zoho Error 204 even for a simple API request like GET Contacts. What should I do?
Start by checking your Zoho user role’s permissions for Contacts module. Also try making the API call from Postman using your credentials to isolate coding issues.

Q4. My API request works fine when testing in Postman but still fails with Error 204 in my code. Why?
There could be a mismatch between actual and coded parameters. Log the request & response from code and compare with Postman to identify the difference.

Q5. How do I check if Zoho Error 204 is caused by a server-side temporary issue?
Make the same API request 2-3 times at intervals of few minutes. If it works sometimes but fails with 204 at other times, it indicates a temporary glitch.

Q6. Should I retry the API request in case of Zoho Error 204 or refresh auth token?
You can retry the request a few times but don’t retry excessively. Check other aspects like permissions first. Refresh auth token only if it has expired.

Q7. I can see the data in Zoho UI but API returns 204 error. Why is this?
Though data is visible in the Zoho app’s UI, the API may apply stricter filters. Try getting records individually by ID via API to check.

Q8. How do I diagnose Zoho Error 204 if neither Zoho support nor forums have relevant answers?
Analyze your API calls case-by-case to identify patterns. Check things like user roles, accessed resources, parameter values etc. for commonalities.

Q9. Will I keep getting Zoho Error 204 if I migrate my Zoho account or switch plans?
No, the 204 error is not caused by account changes. You only need to regenerate your auth tokens and update them in code after account migrations.

Q10. Can Zoho Error 204 occur because of user account deactivation or deletion?
Yes, trying to make API calls using tokens associated with a deactivated or deleted account will lead to 204 errors.

Q11. How do I resume API access after my Zoho account was temporarily blocked?
Reach out to Zoho support to remove the block, then generate new auth tokens and update in your code to resolve Error 204.

Q12. Is there any way to get details about why Zoho API returned 204 error?
Unfortunately the 204 response contains no payload data. You have to rely on other debugging techniques like request logging, testing in Postman etc.

Q13. Should my error handling code treat Zoho 204 same as other 4xx errors?
No, 204 specifically indicates a valid request with empty response. Handle it separately from validation errors like 400, 401 etc.

Q14. Can I disable Zoho 204 errors and make it return full response always?
No, 204 behavior cannot be modified in Zoho. The API returns it intentionally in certain scenarios. Handle 204 properly in your code.

Q15. How can I avoid Zoho 204 errors when launching my application to end users?
Do extensive testing with all use cases to uncover potential 204 errors beforehand. Add proper error handling code with useful messages.

Q16. Is there a way to get Zoho to return a more specific 204 subtype error code?
Unfortunately, Zoho APIs only return the generic 204 No Content error. You have to do your own analysis of the root cause based on request details.

Q17. Should I design my application logic to expect Zoho Error 204?
Yes, plan for 204 and handle it gracefully since you have no control over when Zoho API may intentionally return it. Prevent propagation to end users.

Q18. Can I handle all HTTP status codes the same way in my application or should 204 be different?|
Treat 204 differently from other status codes since it indicates a valid request. Display suitable messages to users compared to say 404 errors.

Q19. If my API request times out, will it also return Zoho Error 204?
No, request timeouts would result in errors like 500 or 504 at the HTTP protocol level, not 204 specifically from Zoho API.

Q20. How should I respond to my application users if I get repetitive Zoho 204 errors?
Notify them about a temporary service issue and suggest alternatives or recovery steps. Compensate users if needed to maintain trust and satisfaction.


In summary, Zoho Error 204 signifies an empty response to an otherwise valid API request. By checking aspects like user permissions, server status, request parameters, etc. as outlined above, you should be able to resolve the majority of 204 occurrence cases. The key is having systematic error handling logic in your code to avoid disruption for end users.

With robust APIs and excellent support, Zoho provides a great platform – overcoming errors like 204 makes integrating Zoho even smoother.
