Steps
Build a batch request payload listing the ticket-to-contact (or ticket-to-company) pairs to associate
Submit the batch with POST /crm/v4/associations/tickets/contacts/batch/create (or /crm/v4/associations/tickets/companies/batch/create)
Stay within the documented cap of 2,000 inputs per batch call, splitting larger association sets across multiple requests
Use the corresponding batch/read endpoint to verify associations were created before relying on them in downstream automation
Remove associations in bulk with the batch/archive endpoint when tickets are merged or reassigned
Known gotchas
The 2,000-input batch cap applies per call — oversized batches must be chunked client-side
Associations v4 endpoints are separate from the older Associations v3 API; don't mix client code written against v3 response shapes with v4 calls
Standard API rate limits (100 requests/10 sec, 250,000/day on Pro/Enterprise) still apply to batch calls even though each call can touch up to 2,000 records
