Pass attribute field as URL parameter

[PaulPetersen1]

I am attempting to launch Field Maps from Survey123 via URL parameter and pass attributes from Survey123 into a specified feature in Field Maps using the using the Field Maps referenceContext=updateFeature method.

The problem is that I can't figure out how to pass a specified attribute from Survey123 as a URL parameter. This is easy to do going from Field Maps to Survey123, but not so much going the opposite direction.

Basically I've got an guid attribute called Pole_Key in Survey123 that matches the GlobalID of a point feature in the Field Map. I want to use that Pole_Key to open and edit the corresponding record in Field Maps. How do I pass the Pole_Key attribute as a URL parameter from Survey123?

Here would be a more dynamic expression:

var itemID = 'xxxxxx'; // Replace with your Survey123 item ID

var field = 'Pole_Key'; // Replace with the appropriate field name

var attributeName = 'RetrofitStatus'; // Replace with the desired attribute name

var attributeValue = '2'; // Replace with the desired attribute value

var survey123UrlSource = 'arcgis-survey123://?itemID=' + itemID + '&field:' + field + '=' + $feature.globalid + '&callback:submit=';

var fieldMapsUrlSource = 'https://fieldmaps.arcgis.app?';

var fieldMapsParams = 'itemID%3D' + itemID + '%26referenceContext%3DupdateFeature%26featureSourceURL%3Dhttps://services1.arcgis.com/xxxx/arcgis/rest/services/xxxx/FeatureServer/0%26';

var featureGlobalID = Mid($feature.globalid, 1, 36);

var featureAttributes = '&featureAttributes=' + URLEncode('{"' + attributeName + '":"' + attributeValue + '"}') + '%0A';

return survey123UrlSource + URLEncode(fieldMapsUrlSource) + fieldMapsParams + 'featureID=' + featureGlobalID + featureAttributes;

Thank you DougBrowning for your answer.

For Field Maps layer,

In Pro, I see the globalID in lower case but with brackets and in AGOL, I see it without brackets.

Is there a solution to manage the callback from Survey to Field Maps even if the globalID from Field Maps is in lower case? Or if there is no solution?

Thank you!

AGOL just hides the brackets but they are there.  It is for sure confusing that Pro, AGOL, ArcMap, 123 and Field Maps are all different.  I have a bug with support on it.

If you are generating the URL with arcade I have seen people use Upper() or Lower() to convert it.  If not Arcade then no I do not know.  In theory GUID does not care but I am seeing it care at times which is weird and a big pain for sure.

Sorry all i got.
