How Odoo API access works, what the Odoo API lets you connect, and when you need a developer to do it properly. Perth, Melbourne, Sydney and Brisbane.
Who this is for
Operations managers, ERP administrators, business owners who want to connect Odoo to other systems and need to understand how its API works before committing to anything.
Question this answers
How do I get Odoo API access and what can I actually connect Odoo to?
What you'll leave with
Odoo uses an API key generated against your user account, used in place of a password with the XML-RPC or JSON-RPC endpoints. The exact screens move around as Odoo updates its interface, so rather than repeat a menu path that may already be out of date, the reliable source is the official documentation: Odoo external API documentation.
Odoo API access runs as a specific user, so it inherits that user's access rights and record rules. An integration that cannot see a record is usually hitting a permission rule rather than a bug.
Treat API credentials like a password. Anyone holding them can read and often write data in your Odoo account. Do not paste them into untrusted tools, and do not send them over email or chat.
The Odoo API gives you programmatic access to the core data in your account. Broadly that covers:
With that access you can push data into accounting or reporting systems, keep records in step across tools, and build dashboards from live Odoo data rather than from exports someone has to remember to run.
Zapier support for Odoo is limited. Zapier coverage is limited relative to what the API exposes, and Odoo has its own automation layer. That is why searches for connecting Odoo through no-code tools tend to turn up workarounds rather than a clean answer.
Connecting Odoo to another system means working through five things, in roughly this order:
A common pairing is Odoo with Xero or Shopify. Read-only reporting is usually straightforward. Live two-way sync is where the mapping and error handling turn it into a proper development project.
Some Odoo API work is genuinely straightforward. Some is not. An honest split:
What you can install and reach differs sharply between the two, and it changes the integration design.
Odoo is usually customised, so the standard field list is rarely the real one.
Odoo makes breaking changes between major versions, and integrations need planning around that.
Odoo posts accounting entries from stock moves, so a naive stock integration can create ledger entries you did not expect.
These integrations look simple from the outside. The work is in the detail: field mapping, conflict resolution, error recovery, and keeping everything in step as both Odoo and the connected system change over time.
If the integration touches invoicing, stock or payroll, getting it wrong has real financial consequences. A properly built integration with monitoring and alerting is worth the upfront cost.
Meet the person
This guide comes from real projects. If it raises a question about your own system, you can ask the founder directly.
HELLO PEOPLE designs, builds and looks after AI, software, app and data solutions for Australian businesses, with senior expertise on every project and a scope agreed before work starts. For an integration, that means every record lands where it should and both systems agree.
Since 2007, HELLO PEOPLE has delivered more than 100 projects from Perth for small and medium businesses across Australia: custom software and apps, system integrations, data migrations, reporting and dashboards, and AI that works inside the systems a business already runs.
I lead every engagement myself. I trained in accounting before moving into IT, hold accounting and IT professional qualifications and an MBA, and bring more than 20 years of experience across sales, service delivery, inventory and compliance. I am also a PhD candidate in AI at Curtin University, researching retrieval-augmented generation (RAG), so the technology is always judged by what it does for the business.
Small and boutique. The person who scopes your integration is the person who builds it, and the same person watches the first live syncs.
No ticket queue and no account manager in between. You hear back within one business day, usually sooner.
The integration is the start, not the end. When you need the next system, integration or report, you call the same person, who already knows your business.
