Edit existing LTI App

[vikas1018]

Hi All,

I have installed one LTI app at account level long back using manual XML option. Now I want to change the launch URL. I tried editing app lauch url using edit option and it does change in url field but is not reflected in actual launch. So despite saving new url, app is launching on old url. I also want to change visibility settings from "admins" to "member".

Sample XML:

<?xml version="1.0" encoding="utf-8"?><cartridge_basiclti_link xmlns="http://www.imsglobal.org/xsd/imslticc_v1p0" xmlns:blti="http://www.imsglobal.org/xsd/imsbasiclti_v1p0" xmlns:lticm="http://www.imsglobal.org/xsd/imslticm_v1p0" xmlns:lticp="http://www.imsglobal.org/xsd/imslticp_v1p0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.imsglobal.org/xsd/imslticc_v1p0 http://www.imsglobal.org/xsd/lti/ltiv1p0/imslticc_v1p0.xsd http://www.imsglobal.org/xsd/imsbasiclti_v1p0 http://www.imsglobal.org/xsd/lti/ltiv1p0/imsbasiclti_v1p0.xsd http://www.imsglobal.org/xsd/imslticm_v1p0 http://www.imsglobal.org/xsd/lti/ltiv1p0/imslticm_v1p0.xsd http://www.imsglobal.org/xsd/imslticp_v1p0 http://www.imsglobal.org/xsd/lti/ltiv1p0/imslticp_v1p0.xsd">

Hi Vikas --

Many of the LTI tool settings can't be changed via the UI once the tool has been installed, but you can change them via the API.  Check out the docs here: 

External Tools - Canvas LMS REST API Documentation 

Postman is a handy tool for working with the REST API: Postman | Supercharge your API workflow

Can anyone help me with the specific API command to rename an existing LTI?

I tried this:

curl -X PUT '<canvasurl>/api/v1/accounts/<accountid>/external_tools/<externaltoolid>' \
     -H "Authorization: Bearer <token>" \
     -F 'name=Asset Library DEPRECATED'

 Which successfully changes the name in the list of apps at the account level, but doesn't change any courses where the app is installed.

Found the answer to my question above:

curl -X PUT '<canvasurl>/api/v1/accounts/<accountid>/external_tools/<externaltoolid>' \
     -H "Authorization: Bearer <token>" \
     -F 'course_navigation[text]=Asset Library DEPRECATED'
