Hello,
I do have value with special character ('&').
Value : 'D&E_Transactions'
I'm using action : 'Invoke web service" parsing the above value.
As the '&' symbol within the value is considered as special character, it is generating status code 400 with webservice response as long HTML format error.
How can I escape '&' to parse here?
I already tried with the action 'Escape text for regular expression' and action 'Replace text' by '&'. But none of these are working.
I'm getting error as below :

Yes, I tried now all above scenarios by storing value as NewVar using Set variable and passing it to Invoke Url.
But still not expected output.
Have you tried to set the whole url into variable and then passing it into Invoke Url section as one variable?
Thank you @Expiscornovus .
I tried with '%2526', but it also doesn't work.
I used %% to escape single % which gave syntax error.
I also tried by applying '%' at both the side.
Tried with single encoded too as suggested in above blog.
Nothing is working here. I'm not sure which syntax should work here.
Just to clarify, api call is working perfectly for the case without special character like '&'.
Thanks @Pavel_NaNoi .
I tried the syntex you suggested here.
It is still throwing 404 error either with single quotes/double quotes.
you can escape a character by putting %'s & double-quotes around it, e.g. %"&"% for things like this.
Hi @Niraj466,
I have seen some people suggesting that you need to encode it twice when interacting with the Web API. Haven't tried it myself but it is worth a shot, right?

Can you try the below instead of the ampersand to see if that works?
