Hi Pabbly team ,


I’m currently integrating Dubb CRM using Pabbly Connect and I’ve run into an issue with updating existing contacts.

What’s working​

• The native Dubb app action to create/update contacts keeps returning Bad Request.
• As a workaround, I successfully used the API module with:
  
  POST https://api.dubb.com/api/v2/contacts
  This creates new contacts correctly when they don’t exist.

The problem​

Once a contact already exists in Dubb, I need to update that same contact with:

• New tags (tier upgrades)
• Possibly other fields (phone, custom fields, etc.)

However:

• Using the same POST endpoint either fails or attempts to create duplicates
• The Dubb API docs aren’t clear on the correct endpoint or method to update contacts
• The Pabbly Dubb app doesn’t expose an “Update Contact” action that works reliably

What I need help with​

1. What is the correct API endpoint + method to update an existing Dubb contact?
   • Should it be PUT or PATCH?
   • Is the contact updated via email, contact ID, or another identifier?
2. How can this be implemented properly inside Pabbly Connect?
   • Should we first search/find the contact in Dubb?
   • Then update it using the returned contact ID?

Use case​

A user purchases different tiers over time:

• Free → Rising Father → Council → VIP
  Each purchase should:
• Add a new tier tag
• Remove the previous tier tag
• Keep the same Dubb contact record

Any guidance or working example would be greatly appreciated
Thanks in advance!

Hi @Iseluleko Ma'at El 0,

You would need to use the Get Contact by Email action step to fetch the contact ID.

Then pass that contact ID to the Update a Contact action step. This will allow you to update the details of an existing contact.

===============================================================

For some reason, you are encountering a Bad Request error in the Dubb: Update a Contact action step. Please allow our technical team some time to look into this issue. We will get back to you with an update soon.
