Hello, I would like to use the Ripe api : /api/v2/measurements/{msm_id}/participation-requests/{source_id}/. for getting measurement results, but I keep getting the following error (in the picture). Here is the website of the different apis: https://atlas.ripe.net/docs/api/v2/reference/#!/measurements/Type_0_1_2_3_4_... Is it due to my key? Knowing that I have already used it to create measurements and get measurement results and in other apis from Ripe. Concerning the example below, I have checked the measurement ID and that the probe in the source ID figures among the participant probes. I don't quiet see the source of the problem, do you have any ideas about this? Thank you, Cheers, Sanaa
