For bulk service activation, there is no TMF Open API that natively supports file-based activation of 50Kβ100K services/numbers in a single request. TMF APIs are generally entity-oriented and expect standard request payloads rather than large file uploads. [tmforum.org], [engage.tmforum.org]
A common TMF-aligned approach is:
Use TMF641 Service Order (or the relevant Service/Product Order API) and model multiple numbers as order items when volumes are reasonable.
For very large volumes, implement an asynchronous Bulk Import/Job pattern (custom extension), where a file upload creates a job, the backend processes the file, and individual service activations are orchestrated internally.
Keep the TMF API contract standards-compliant so CTK validation remains focused on the standard API behavior.
In short: No standard TMF bulk activation API exists for 50Kβ100K records; use TMF order APIs plus an asynchronous bulk-job orchestration pattern
