Dubb integration: Create contact works via API module, but how to UPDATE existing contacts with new data?

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.
