ServiceM8 API – Historical Job Data, Queue Events & Reporting Questions

Developer API & SDK
1

We’re developing a read-only management reporting add-on and I’m trying to establish which historical data can be obtained reliably through the supported API.

Has anyone implemented the following using the ServiceM8 API/Add-on Kit?

  1. Original job creation timestamp: Is there a reliable immutable creation timestamp separate from Job date, which may represent created/scheduled date?

  2. Issued invoice/quote history: Is there an endpoint/object that provides actual issued quote/invoice versions, issue timestamps, ex-tax/tax totals, credits and partial invoices, rather than relying on current Job totals?

  3. Queue history: Can historical queue entry/exit transitions be retrieved, or does this need to be captured prospectively from job.queued / other events? If you’ve used job.queued, what payload does it provide?

  4. Native Xero tracking category: Is there a supported way to retrieve the ServiceM8 Xero tracking-category selection other than observing customfield_xero_tracking_cat_1 on the Job object?

  5. Incremental synchronisation: Do changes to child records such as materials/invoices update the parent Job edit_date, or should each relevant object type be independently synchronised?

I’m looking specifically for supported API behaviour or practical experience rather than implementation advice. Example responses/endpoints would be appreciated.
