Odoo API integrations: connect your ERP with the rest of your business
Your business doesn't run on a single tool. You take payments through a payment gateway, send items with a courier, sell on marketplaces, talk to customers on WhatsApp, and reconcile movements with the bank. When each piece works on its own, someone ends up copying data manually from one place to another, with all the errors and wasted time that entails. Odoo API integrations allow all those tools to communicate with each other automatically, with Odoo as the central hub organising the information. On this page, we explain, in business terms, what an API integration is, what it's for, and with what real-world examples you can start.
What it means to integrate Odoo with other tools
An API is, simply put, a communication gateway that a program opens so that other programs can request information from it or send data to it in an organised manner. When we say that Odoo integrates with another tool via API, we mean that both systems exchange data automatically, without anyone having to export a file, open another screen, and retype it.
The practical result is that an order from your online shop, a payment from the gateway, or a shipment from your carrier appear in Odoo automatically, updated and almost in real-time. Odoo is designed for this as standard: it offers standard connectors for many platforms and an open API to create custom integrations when the business needs them.
Odoo API integrations can be approached on two levels. The first is the ready-made connections offered by Odoo itself or its ecosystem (payments, shipments, electronic accounting). The second is custom integrations, when you work with a provider or a tool that doesn't have a standard connector and they need to be linked point-to-point.
What integration is for: less manual work, fewer errors
The underlying reason for any integration is always the same: to stop moving data manually. Every time someone copies an order, a payment, or an address from one application to another, time is lost, and the risk of error increases. With Odoo's API integrations, that data travels automatically and remains consistent in a single place.
This translates into concrete benefits for an SME: the administration team stops spending hours on repetitive tasks, stock reflects what is actually available because it is updated with every sale from every channel, and management has reliable data to make decisions, instead of spreadsheets that no one knows if they are up to date.
Integration is also the basis for taking another step towards automation. Once information flows between systems, you can chain automatic actions on it. We elaborate on this on our Odoo AI automation page, where you'll see how to move from connected data to processes that run themselves.
Payment gateways and banks
Payment gateways are one of the most common integrations. Odoo connects with widely used gateways so that when a customer pays in your shop or an online invoice, the payment is automatically registered, and the order progresses without manual intervention. The customer gains the peace of mind of a recognised gateway, and you save yourself reconciling payments one by one.
With banks, the usual integration is bank reconciliation. Odoo can import your account movements and help you match them with invoices and payments, so that seeing what has been collected and what is pending stops being a tedious task at the end of the month. The availability of a direct connection depends on each bank and the file format or service it offers.
Regarding gateway costs and commissions, each provider applies its own rates and conditions. Any specific figure should be checked on the official website of the payment provider or bank; what we indicate here is only an indicative estimate, not binding.
Couriers, shipments and marketplaces
In logistics, Odoo integrates with couriers and carriers to calculate shipping rates, generate labels, and return the tracking number to the order. Thus, preparing a shipment no longer means going to the carrier's website and copying addresses; it's done from within Odoo, and the customer receives their tracking without intermediate steps.
In sales, integrations with marketplaces are increasingly in demand. Connecting Odoo with the channels where you sell allows you to centralise all orders in a single place and, above all, keep stock synchronised so you don't sell what you no longer have. Depending on the marketplace, the connection can be direct or require a specific Odoo ecosystem connector.
In customer communication, it's also common to integrate messaging channels like email, SMS, or chat apps, so that order, tracking, or incident notifications are automatically sent from Odoo. The goal is for every interaction to be registered with the customer, without leaving the system.
Standard integrations versus custom integrations
Not all integrations cost the same or require the same work. When there is a standard connector for the tool you use, getting it up and running is usually quick: it's configured, tested, and activated. It's always the first option we consider, because it's the most affordable and easiest to maintain over time.
When you work with a tool that doesn't have a standard connector (proprietary software, a specific provider, an old ERP you're migrating from), the integration is built to measure using the Odoo API. Here, an honest upfront analysis pays off: what data needs to move, in what direction, how often, and what happens if something goes wrong. This analysis is part of our Odoo consultancy, where we define the real scope before writing a single line of code.
Every integration, standard or custom, is deployed within an organised project. If you're starting with Odoo, the connection of your tools is planned as part of the Odoo implementation, so that each integration arrives at the right time and without interruptions to your daily routine.
How we approach it at Nextdoo
As an Official Odoo Partner based in Cunit (Tarragona) and covering all of Spain, at Nextdoo we treat Odoo API integrations for what they are: the way for your business to stop working with islands of information and move to a single coherent system. We always start by understanding your operations and priorities, not by listing technologies.
Our practical recommendation is to start with the integrations that provide the most relief today (typically payments, shipments, or the main sales channel) and expand in phases. This way, you see results soon, the team adapts without pressure, and the project stays under control in terms of time and budget.
If you want to know which integrations make sense in your case, the first step is a conversation to review your current tools and identify where you are losing time copying data manually. From there, we propose a realistic plan based on priorities.

Frequently asked questions
What exactly is an API integration in Odoo?
It's a connection that allows Odoo and another tool to exchange data automatically, without manual copying. For example, a payment from the payment gateway or an order from a marketplace appearing in Odoo automatically, updated and almost in real-time.
What types of tools can Odoo integrate with?
With payment gateways, banks for reconciliation, carriers and couriers, marketplaces and online sales channels, and communication applications like email, SMS, or chat. Many have a standard connector; for the rest, a custom integration is built with the Odoo API.
Do I need standard connectors, or does it always have to be custom programmed?
It depends on the tool. When a standard connector exists, setting it up is quick and affordable, and it's always the first option we consider. Custom development is only used when no connector is available for the specific system you are using.
How much does it cost to integrate Odoo with my tools?
The cost varies greatly depending on whether there's a standard connector or if custom development is needed, and on the number of systems and data volume. We don't provide fixed figures without analysing your case; any indicative amount would be an estimated reference, not binding. Gateway or bank commissions are set by each provider on their official website.
Where do I start with integrations?
With those that save you the most time today, usually payments, shipments, or your main sales channel, and you expand in phases. This way, you see results soon, and the project stays under control. At Nextdoo, we plan it as part of the implementation or consultancy, depending on your starting point.
