A package and permissions are required to do this.
Follow these steps to add a Resource to a Data Connector:
1.​View your Data Connectors. The Data Connectors page displays.
2.Click the Edit icon
for the Data Connector to edit. The Resources tab displays Resources configured for this Data Connector.
 
3.Click the +Resource button. The Create Resource screen displays.
 
4.In the Name setting, optionally edit the purpose for this Resource and how it interacts with that data source's endpoint. The value the Name setting displays from the ProcessMaker asset when configuring the Data Connector from that asset. For example, a Resource with the name Get Values displays that name when configuring a Select List control to use this Data Connector to indicate the Resource's purpose. Therefore, provide a concise but relevant name for this Resource so other ProcessMaker designers understand its function. List is the default purpose for a new Resource.
5.In the Description setting, enter a description of this Resource. Descriptions do not display from ProcessMaker assets when configuring them with a Data Connector.
6.From the Method drop-down menu, select the method how this Resource interacts with the data source from one of the following options:
GET: The GET method retrieves data from the data source.
POST: The POST method creates data in the data source.
PUT: The PUT method does one of the following:
Update: The PUT method updates data in the data source if the specified endpoint's value exists in the data source.
Create: The PUT method creates data in the data source if the value does not exist that corresponds with the specified endpoint.
PATCH: The PATCH method partially modifies data in the data source that corresponds with the specified endpoint.
DELETE: The DELETE method removes data from the data source that corresponds with the specified endpoint.
7.In the URL setting, enter the URL and any required/optional parameters to interact with that data source's endpoint. If configuring this Resource to make a request (contact) to our API, understand how to make a request with your ProcessMaker API instance, and then consult our API documentation to understand any parameters for the  endpoint to which this Resource interacts. The URL setting supports mustache syntax to reference the value of a Request variable as the URL and/or parameter setting. To understand any required or optional parameters for a third-party data source's endpoint, consult that data source's documentation.
8.Click Add. A new Resource is created. 
 
9.Do one of the following:
Optionally, add parameters to this Resource. The parameter(s) are sent to the data source's endpoint when this Resource interacts with that endpoint. See Add Resource Parameters.
Optionally, add headers to this Resource. The header(s) are sent to the data source's endpoint when this Resource interacts with that endpoint. See Add Resource Headers.
Optionally, add a body to this Resource. The body is sent to the data source's endpoint when this Resource interacts with that endpoint. See Add a Resource Body.
Add Resource Parameters
A Resource may send Request data as parameters when that Resource connects to the data source's endpoint so that the endpoint may process that Request data prior to its response.
Do not send Request data to a data source other than our API. A third-party data source cannot recognize the Request data.
Follow these steps to add parameters to a Data Connector's Resource:
1.​Add or view the Resource for the Data Connector to which to add parameters. The Configuration tab displays basic configuration settings for that Resource.
2.Click the Params tab.

6.Select the Required setting if this key requires a value. If the Default setting contains mustache syntax to derive its value from a Request variable, then the referenced Request variable must exist in the Request data and must not be empty. This setting is not selected by default.
7.Click Save.
8.Click Save again in the Params tab to save the recent changes.
Add Resource Headers
A header is part of the Data Connector Resource's interaction with a data source's endpoint that contains metadata regarding that interaction. A header is included when a Resource makes a request to (contacts) the data source endpoint; likewise, the endpoint includes a response header that is included when that endpoint responds to that request. Headers are used to provide information to both the Data Connector and the data source. Headers can be used for many purposes, including authentication and providing information about the body content of the request/response.
Headers are key-value pairs that are separated by a colon (:). For example, the Content-Type header option below indicates to the data source to expect the Resource's content to be JSON.
"Content-Type: application/json"
See this list of header options that may be used in a Resource's header.
Each header option added to a Resource is included in the request when the Resource makes its request to the data source.
