Get Access

Before integrating, you'll need to set up a new user account in Fourth with access rights to the API and resource.

Requests to the Requisitions resource are not restricted by property. This means you can retrieve requisitions data for properties in which the user account is not present.

Step 1: create a user group 

Create a user group for accessing the API within one of your Fourth properties — we recommend the central purchasing property where there is one. 

Screenshot showing the Group Details screen. Under "Edit Permissions", the "API Access" option is ticked.

For security, we also recommend that you limit the user group to access to just the “Requisitions API”. The setting for this is within the user group's Property > API Access sub-section. The group only needs the view option.

Step 2: create a user account

In the same property, create a user account. Assign it to the API user group.

Getting the property number

You’ll need the property number of your Adaco properties before you can make an API request. You can find the property numbers in the Fourth UI.

Units of Measure

The response to requests includes an IssueUnit field. This returns predefined values you can find in the Units of Measure table.

Resources path

Details for integrating with the resource are available in the Adaco Web API reference.

The resource supports GET requests only. The path for Requisitions requests is:


You need to put your customerName in the URL path — this is the same name in the URL that you currently use to log into Fourth Inventory for Hotels. You also need to add "Service" to the name; e.g. "acmeService".

Request header

For all requests, you must provide your authentication details using Basic authentication in the header. Example header:

GET /{customerName}Service/WebApi/Requisitions/{propertyNumber}  HTTP/1.1
Authorization: Basic VXNlcm5hbWU6cGFzc3dvcmQ=
Content-Type: application/json
Field Description
Authorization Your Requisitions API username and password, separated by a colon, and then base64 encoded. Your ID and password are case-sensitive. 
Content-Type The data format you are using for POST request. Options are: application/json, text/json.

Filtering requests

There are four optional parameters which can be included in the URL query string: pageSize and page let you determine how many requisitions you want returned in the response, while status and modifiedsince let you filter the responses.

For example, this request gets pending requisitions from and to property 12345. The request specifies the 3rd page of results, where each page holds 10 records:

GET <ROOT>/ACMEService/WebApi/Requisitions/12345?pageSize=10&page=3&status=pending

See the Adaco Web API reference for a full description.
