When to use this.

The "Create CRM Association (HubSpot)" action enables users to establish relationships between different CRM objects within HubSpot, such as linking a contact to a company or associating a deal with a contact. This action requires three key input parameters: 'fromObjectId' (text), which identifies the primary object being associated (e.g., Contact ID); 'toObjectId' (text), which specifies the secondary object to associate with (e.g., Company ID); and 'definitionId' (select), which determines the type of association being created. Upon execution, the action returns a 'success' output (boolean) indicating whether the association was successfully established. This functionality is particularly useful for businesses looking to enhance their CRM data relationships, streamline sales processes, and improve customer management by ensuring relevant objects are interconnected. As part of the CRM category, this action is essential for organizations aiming to optimize their HubSpot usage and improve overall data integrity.

FAQ.

  • Is this real-time?

    Yes. Synchronous actions return in ~1–4 s. Long-running work uses async polling (see status 504 → switch to async).

  • Do I get charged on failure?

    No. Verified failures cost zero credits. Provider miss / 5xx / timeout cascade to the next provider in the waterfall when applicable.

  • Does it work with Claude / Cursor via MCP?

    Yes. Add the texau MCP server to your client config, then call `texau__hubspot-...` directly.

  • What CRMs can I push results to?

    HubSpot, Salesforce, Pipedrive, Zoho, and GoHighLevel are bidirectional. Smartlead, Instantly, Lemlist, HeyReach, Apollo Sequences, and Reply.io for outbound.
