Power Automate - Combine 2 or more http responses

(0) Share

Report

Posted on by jim_beam

Hi - hoping that someone can help with the following:

I have an http request that returns more that 999 items:

https://graph.microsoft.com/v1.0/users?$select=displayName,id,officeLocation,assignedLicenses,licenseAssignmentStates&$top=999&$count=true&$filter=startswith(officeLocation,'TEST')

Ultimately, the data will be sent back to a canvas app as text using "Respond to a PowerApp or flow".

I have read and testing combining the 2 replies using pagination information, selecting the specific information that I need, and looping through the results adding each to an array. The concern, as I have also seen others mention, is that appending to array can take a considerable amount of time. In my case, ~ 2 minutes for each 999 records. [I already set the speed option to 50]

Questions:

Is there a fast way to combine 2 or more HTTP responses without appending to array

Is there a way to get more than 1000 records for the http request mentioned above? In my case, I am using just a free Http connector

Does this result come in an array? Or maybe post a sample of the result

Hi

Thank you for the reply. A sample below showing that the results do come in an array. Sample below shows 1 name.
I need to pull 1500 names which exceeds the 1000 limit and hence the need to concat 2 http responses

{
"@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users(displayName,id,officeLocation,assignedLicenses,licenseAssignmentStates)",
"@odata.count": 659,
"@odata.nextLink": "https://graph.microsoft.com/v1.0/users?$select=displayName%2cid%2cofficeLocation%2cassignedLicenses%2clicenseAssignmentStates&$top=9&$count=true&$filter=startswith(officeLocation%2c%Test%27)&$skiptoken=0000",
"value": [
{
"displayName": "Jim_Beam",
"id": "000",
"officeLocation": "Test",
"assignedLicenses": [
{
"disabledPlans": [],
"skuId": "000"
},
{
"disabledPlans": [],
"skuId": "000"
},
{
"disabledPlans": [],
"skuId": "000"
},
{
"disabledPlans": [],
"skuId": "0000"
}
],
"licenseAssignmentStates": [
{
"skuId": "000",
"disabledPlans": [],
"assignedByGroup": "ggg",
"state": "Active",
"error": "None",
"lastUpdatedDateTime": "2001-08-22T17:14:42.6958845Z"
},
{
"skuId": "000",
"disabledPlans": [],
"assignedByGroup": "0000",
"state": "Active",
"error": "None",
"lastUpdatedDateTime": "2001-05-12T19:27:10.0947329Z"
}
]
}
]
}

Okay, you can use the union function in a Compose action
union(outputs('Your_Graph_Action')[0]['value'],outputs('Your_Graph_Action')[1]['value'])
If you are not sure about the number of pages your results will contain (or you want to account for any number of pages), then it gets a little bit more complicated.

First, compose a unique string using the GUID function. This will come in handy later.
Second, use the Select action to extract all the value arrays (each page will have a value array) from the results. Here you switch the Map to text mode and add
item()['value']
FInally, add this expression to a compose action to combine the arrays.
json( replace( join(body('Your_select_action'),outputs('ComposeGUID')), concat(']',outputs('ComposeGUID'),'['), ',' ) )

Ok, so I did some digging on the Microsoft Graph API:
I can't seem to run a similar query to yours on Power Automate but I can at least run some queries on the /users segment on the Graph Explorer (go figure).

I'm using the Send an HTTP request (Preview) action as it does not require a premium license. So I don't know if it's the same action you are using.
Initialize a string variable for your query. You'll be updating this variable with the next link if any.

In a do until loop, send your request with the query you set earlier, then convert the value array into string. Update the Query variable with the next link (if any)
body('Send_an_HTTP_request')?['@odata.nextLink']
Compose the combined output with this expression
json(replace(variables('Results'),'][',','))

Thank you very much!! I tried the union function and it works amazingly [quick]. I do not fully understand the second option that you provided, but will play with it later. Thank you again for your help. Much appreciated

For what its worth - to make the query work, I needed to add Request header "ConsistencyLevel:eventual"

Hi! I am struggling with the select value step.

Just to confirm you put the outputs from Parse Json as the "from" field and just item()['value']. (In my case I replaced value with records as that is what is shown in my outputs.

Your data structure may be different. I'm guessing each item under records is an array?
{ "body": { "uri": "http...", "records": [ [...], [...] ] } }
If the above structure is correct, then all you have to do is use this expression in a Compose action. No need for Select.
json( replace( join(body('Your_action')?['records'],outputs('ComposeGUID')), concat(']',outputs('ComposeGUID'),'['), ',' ) )

Thank you, what we ended up doing is putting the entire pull into a for each loop and repeating it until there is no more next page.
