Odoo rest API

• First of all, we have to add a new parameter in odoo conf. file.
• server_wide_modules = web, base, rest_api_odoo
  - This will allow us to send request to server without selecting database first.
  - Incase if you have to uninstall the module , you have to remove this parameter.
  - Next we can install the module.
• After installing the Rest api app we can see a new api key field in users.
- Next we have to generate the api-key for the current user.

• You can import the postman collections provided in the app folder for authentication and interacting with database in various methods.

• We have attached Postman collections through which you can authenticate rest api.
• First, extract the zip file. Then, you will obtain the JSON-format file, which you can directly import into POSTMAN.
• The url format will be like this - http://localhost:8017/odoo_connect Replace 'localhost:8016' with your localhost port number.
• You have to provide database name, username and password through the headers while sending request.
• If the authentication is successful , an api key will be generated for the current user.
• This key will be used when sending api requests to database.
• The response will be like this - {"Status": "auth successful", "User": "Mitchell Admin", "api-key": "66c2ebab-d4dc-42f0-87d0-d1646e887569"}.

• After rest api authentication, we can create records in the rest api app.
• Here we can choose the model, and also we can choose the http methods.
• The api response will be based on these records.

Get Records

• You can send GET request to retrieve data from the database.
• The postman collection has been provided with--> app files for sending request from postman.
• You have to provide username, password and api key through the header.
• Model can be passed as argument as the technical name , and also if you want specific record you can provide the id as well,
• The format for GET method will be like this http://localhost:8016/send_request?model=res.partner&Id=10.
• We can specify the fields inside the JSON data, and it will be like this - {"fields": ["name", "email"]}.
• This is the format of api response - {"records": [{"id": 10, "email": "deco.addict82@example.com", "name": "Deco Addict"}]}.

Create Records

• Using POST method , you can create new records in the database.
• Just make sure you enabled POST method for the model record in rest api app , otherwise you will get 'method not allowed' message.
• For creating record you have to provide the JSON data along with the model.
• You can make use of the postman collection that we have added with app files.
• The format for sending POST request will be like this - http://localhost:8016/send_request?model=res.partner.
• This is the format for JSON data - { "fields" :["name", "phone"] , "values": {"name": "abc", "phone":"55962441552" } }.
• Make sure the data entered in correct format otherwise you will get 'Invalid JSON data' message.
• Response will be in this format - {"New resource": [{"id": 51, "name": "abc", "phone": "55962441552"}]}.

• Updation of records in the database can be done with PUT method.
• You have to provide the model and also the id or the record that you want to update.
• You can use the Postman collection that we have provided and , you will be always have to send request with your login credentials. Otherwise, it will be showing access denied.
• The format for sending PUT request will be like this - http://localhost:8016/send_request?model=res.partner&Id=46.
• Here too you have to provide the JSON data through which the updates will be done.
• The response format will be like this - {"Updated resource": [{"id": 46, "email": "abc@example.com", "name": "Toni"}]}.

• Database records can be deleted by sending DELETE method request.
• For the deletion we have to provide the Model and the record id that we want to delete.
