LTI missing consumer key?

LTI missing consumer key?

Number of replies: 6

Hello,

I have two moodles setup (moodle32 and moodle33); moodle32 is the LTI provider and moodle33 is the consumer.

On the provider, the cartridge URL is: http://moodle32.lms.xxxxxx/enrol/lti/cartridge.php/3/713f367107aa5d5f72d3fa2aeaf6e5e7/cartridge.xml

On the consumer, that has been added to a course as an "Add external tool" activity

I've added the cartridge URL and secret, and the tool URL is now showing as http://moodle32.lms.xxxxxx/enrol/lti/tool.php?id=3

However, when I click on "save and display", I get the correct IFRAME and activity title, but the IFRAME content is "A required parameter (oauth_consumer_key) was missing"

Where and how is the consumer key defined on the provider moodle?

Thanks

N

I enabled full debug information on the provider moodle, and I get this information:

A required parameter (oauth_consumer_key) was missing

Hi do you have the Consumer Key filled out in the External Tool activity form on the Consumer site?

Hi

No, I haven't; that is the problem.  I can't see where that is defined on the provider site. I can see the 'secret key' but not the 'consumer key'

Thanks

Ah. Excellent. I just realised!

The consumer side can set the key to be anything.

What did you realise Nick?

We have the same issue and have not found the solution yet.

Thanks in advance!

Dat is grappig Irma... Ik loop nu ook tegen dit issue aan? Heb jij op een andere manier al een antwoord gevonden?
