Hi,

We are doing an integration with Hubspot Api, but we need the Json or Swagger definition of these two end points:

**[https://api.hubapi.com/deals/v1/deal](https://api.hubapi.com/deals/v1/deal)**  
**[https://api.hubapi.com/contacts/v1/contact/batch/](https://api.hubapi.com/contacts/v1/contact/batch/)**

Do you know where we can find these definitions?

Many Thanks and regards

Hey @sergiopascual ,

We don’t currently have swagger definitions for these APIs, but our developer documentation for each has example JSON:

[https://developers.hubspot.com/docs/methods/deals/create\_deal](https://developers.hubspot.com/docs/methods/deals/create_deal)

[https://developers.hubspot.com/docs/methods/contacts/batch\_create\_or\_update](https://developers.hubspot.com/docs/methods/contacts/batch_create_or_update)

Does that answer your question?
