# ServiceNow
2+
3+
## Summary
4+
5+
A set of templates to perform operations against a ServiceNow instance.
6+
7+
### Compatibility
8+
9+
The workflowTemplate have been tested on the following instance releases:
10+
11+
* Washington DC
12+
13+
## Requirements
14+
1. Create a secret containing 2 pieces of information to connect to your
15+
ServiceNow instance. See [example](../../assets/sn_auth.yml)
16+
- username
17+
- password
18+
See the [example](../../assets/sn_auth.yml) for more details.
19+
20+
The user needs change_management permissions.
21+
22+
2. Create a secret containing the Codefresh API Key (in the token field). See
23+
the [example](../../assets/cf_token.yaml) for more details.
24+
3. install the [local update](../../assets/xml/ServiceNow-Codefresh_Integration_1.3.1.xml)
25+
set in your instance using the Retrieve Update Sets table. Check with your
26+
ServiceNow admin if you're not sure or don't have enough permissions. The
27+
architecture is detailed in this
28+
[old blog article](https://codefresh.io/blog/servicenow-integration/).
29+
30+
## Templates
31+

32+
1. [updatecr](https://github.com/codefresh-io/argo-hub/blob/main/workflows/servicenow/versions/1.4.0/docs/updatecr.md) - Modify an existing Change Request
33+
1. [closecr](https://github.com/codefresh-io/argo-hub/blob/main/workflows/servicenow/versions/1.4.0/docs/closecr.md) - Close an open Change Request
34+
35+
36+

39+
40+
