This version of the connector is outdated. Show recent version
The Rest API Connector allows you to communicate with other REST services using the HTTP protocol with basic request types, i.e. GET
, POST
, PUT
, PATCH
and DELETE
. It also supports many of the most commonly used authentication methods (OAuth2
, Token
, NTLM
,...).
DataContentType
The format that will be used for the content of the request body and also for the response (Content-type
and Accept
will be set to application/xml
by default). To override the preferred response body format, use the Headers
configuration section and insert the Accept
key with the value application/xml
to use JSON as the preferred response body format.
Data
The request body, which should be of the type defined in the DataContentType
field (XML, JSON,...) or defined using the Content-Type
HTTP header, which can be filled in the Headers
property.
Accessing input data
If the input schema is selected, it's data can be accessed by following placeholders:
Placeholder | Description |
---|---|
${input} |
Replaced by whole input |
${input.property} |
Replaced by single cell of input |
Using placeholders
Placeholders can be used to dynamically create the contents of the request body
or to modify the configuration.
Input data can be referred by using placeholders:
${input.ObjectID}
will be replaced by the value in theObjectID
property of the input data connector.${input}
will be replaced by the integer value of the input data.
Placeholders for creating body content
The body content can be configured directly or can be generated based on the input using placeholders. The resulting JSON or XML (based on configuration) will also take into account the data type of the input columns. For example, the numbers in the JSON are as numbers (without double quotes).
Assume the connector input data is in the following format:
ID (Number) | Name (String) | Items (Complex) |
---|---|---|
1 | Alice | [{"ID":1},{"ID":2}] |
2 | Bob | [{"ID":3},{"ID":4}] |
Examples of using single cell
placeholders to create a request body
for the JSON
format. You can also serialize Complex
or JSON
types in this way.
{
"CustomerID": ${input.ID},
"CustomerName": ${input.Name},
"IsActive": true,
"ItemIDs": ${input.Items}
}
will generate request body
[
{
"CustomerID": 1,
"CustomerName": "Alice",
"IsActive": true,
"ItemIDs":
[
{"ID":1},
{"ID":2}
]
},
{
"CustomerID": 2,
"CustomerName": "Bob",
"IsActive": true,
"ItemIDs":
[
{"ID":3},
{"ID":4}
]
}
]
or whole body
placeholder
${input}
generates the following request body
that uses the property names as column names from the input schema
[
{
"ID": 1,
"Name": "Alice",
"Items":
[
{"ID":1},
{"ID":2}
]
},
{
"ID": 2,
"Name": "Bob",
"Items":
[
{"ID":3},
{"ID":4}
]
}
]
for input where there is only one line, the following placeholder
${input.Items}
generates an array of rows of type Complex
[
{"ID":1},
{"ID":2}
]
or XML
format supports single cell
placeholders so following settings
<Customer><Name>${input.Name}</Name></Customer>
will generate
<Customer><Name>Alice</Name></Customer>
<Customer><Name>Bob</Name></Customer>
with a combination of XML header
and XML footer
. It can generate the following XML where the Root
element Customers
is used.
<Customers>
<Customer><Name>Alice</Name></Customer>
<Customer><Name>Bob</Name></Customer>
</Customers>
Placeholders for other configuration properties
You can use the single cell
placeholder for other string configuration properties, which can be wrapped with additional text.
This allows you to dynamically change the path
of the request for the endpoint. But for these configuration properties, the placeholders
are replaced only by the first line of input data.
Example
api/endpoint/${input.Method}
Basic request types
The following table lists the supported HTTP methods. Additional configuration options are available based on the selected request type
Request type | CRUD |
---|---|
POST | Create |
GET | Read |
PUT | Update / Replace |
PATCH | Update / Modify |
DELETE | Delete |
Headers
Specify custom headers to be used with the HTTP request in the form of key/value pairs. For more information, see this link HTTP documentation.
It is not necessary to specify all headers, some are default based on the chosen data content type (Accept
, Content-Type
).
Header Key | Value | Description |
---|---|---|
Accept | application/json | format of response which will be received (requested API must support this) |
Content-Type | application/json | content body format to be used |
Endpoint
The endpoint specifies a Path
with parameters to query the requested resource from the Host
defined in the connection configuration. The combination of Host
and Path
is the requested URI.
Example
- api/endpoint/getData?dataId=1
- api/endpoint/create
Input data can be referenced using placeholders, i.e. ${input.ObjectID}
will be replaced by the value in the ObjectID
property of the input. However, except for the Data
configuration, this placeholder only works when the input has a single line.
Example
api/endpoint/${input.Method}
Configuration
Rest API connection
Base URL
The base URL of the connection. The request uses a combination of the Base URL
in this parameter with the Endpoint
URL path.
Base URL and Endpoint URL path in the System
If you input an absolute path into both the Base URL and Endpoint URL path, the system simply concatenates them as strings, potentially resulting in unsuccessful endpoint calls.
https://dx.xeelo.net
Input data can be referenced using placeholders, i.e. ${input.ObjectID}
will be replaced by the value in the ObjectID
property of the input. This placeholder only works when the input has a single line.
https:/server.com/${input.Uri}/
Ignore SSL Certificates
If set, will ignore SSL certificates. Can be used if the remote API does not have a signed certificate.
Authorization Method
Supported authorization methods:

- NTLM Ticket - More secure than just NTLM, credentials are negotiated for the access token. No need to send credentials for every request (see Documentation).
