OpenAI sunsets the Assistants API: What it means for your Zoho SalesIQ integration
OpenAI sunset the Assistants API on August 26, 2026, as it moves agent-based applications to its newer Responses API and Conversations API architecture.
If you already use an OpenAI Assistant through Zoho SalesIQ, you may be wondering what this means for your existing setup.
The short answer: There's nothing you need to migrate manually.
SalesIQ has already updated its underlying OpenAI integration to support the newer architecture, so your existing configuration can continue working without requiring you to recreate your existing Assistant, rebuild bot flows, or make changes to your SalesIQ setup.
SalesIQ has handled the migration for you
SalesIQ's integration with OpenAI has been updated to work with the newer Conversations + Responses architecture behind the scenes.
If you already had an OpenAI Assistant configured with SalesIQ, your existing setup is carried forward through the migrated integration. Your existing Assistant IDs, conversation IDs, and file IDs continue to work within the SalesIQ-managed integration.
The ChatGPT-powered capabilities you use today—including Conversation Summary, Writing Assistant, Tags Generation, Smart Suggestions, and the ChatGPT card in the Codeless Bot Builder—continue to work as before.
Underlying capabilities such as code interpreter, and file search also continue to work.
This means you don't need to:
- Recreate your existing Assistant
- Change API calls within SalesIQ
- Reconfigure your existing ChatGPT integration
- Rebuild your Zobot flows
For customers who already had an Assistant connected to SalesIQ, the migration is handled behind the scenes.
What happens to existing conversations?
Existing conversations created before the upgrade are migrated automatically the next time they're used.
No manual migration is required.
To preserve recent context, SalesIQ carries over the latest 100 messages from the existing conversation when it's migrated. Messages beyond this limit aren't carried over.
If a migration can't be completed during an interaction, the existing conversation state is retained and the migration is retried automatically the next time the conversation is used.
For developers: One change to be aware of
If you've built a custom implementation that retrieves conversation messages programmatically using the GET messages endpoint, there's one response-format change you should be aware of.
Previously, the messages array contained only user and assistant text messages.
With the newer architecture, the response may also include activity items generated during a response, such as:
- File search calls
- Code execution
- Function calls
- Reasoning summaries
If your implementation only needs user and assistant messages, filter the response for items where the type is message.
This lets your application continue processing text messages as before.
If you want to surface more information about what happened during a response, the additional activity items are also available to you.
What if you use OpenAI's Assistants API outside SalesIQ?
The automatic migration described above applies to the SalesIQ-managed OpenAI integration.
If you have another application, custom integration, or service that calls OpenAI's Assistants API directly, that implementation is separate from SalesIQ and will need to be migrated to OpenAI's Responses API.
For the steps involved, refer to OpenAI's official Assistants-to-Responses migration guide.
Quick reference
Do I need to migrate anything in SalesIQ?
No. If you're using the SalesIQ-managed OpenAI integration, the migration has already been handled for you.
Do I need to recreate my existing Assistant?
No.
Will my existing Assistant IDs, conversation IDs, and file IDs continue to work?
Yes, within the SalesIQ-managed integration.
Do I need to rebuild my Zobot flows?
No, if you're using an existing Assistant configuration that was already connected to SalesIQ.
What happens to existing conversations?
They are migrated automatically the next time they're used.
What if I don't already have an OpenAI Assistant connected to SalesIQ?
If you already had an Assistant configured with SalesIQ, your existing setup continues to work through the migrated integration.
If you don't already have an Assistant connected, creating a new Assistant-based setup is temporarily unavailable following OpenAI's Assistants API sunset.
We're working on bringing the ability to create and update Assistant configurations directly into the SalesIQ integration console. Once available, new and existing customers will be able to manage these configurations directly from SalesIQ.
How much conversation history is preserved during migration?
The latest 100 messages from the existing conversation are carried over.
Which data centers support the ChatGPT integration in SalesIQ?
US, EU, IN, JP, and AU.
What OpenAI plan do I need?
You'll need an OpenAI account with API access. A ChatGPT Plus subscription is separate from OpenAI API access.
