FastLink Update Site Flow results in blank iFrame

I am able to follow the FastLink Integration Guide for the Add Site flow to successfully generate an "add site" page in an iFrame and link up a new site account. However, when I follow the instructions for "update site", it results in a 200 response and a blank iFrame. Here's an example URL I generated:

https://fastlink.yodlee.com/appscenter/fastlinksb/prepareEditSiteAccounts.fastlinksb.action?access_type=oauthdeeplink&displayMode=desktop&oauth_callback=oob&oauth_consumer_key=a458bdf184d34c0cab7ef7ffbb5f016b&oauth_nonce=Uz0DvzJdBJG&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1411681723&oauth_token=fdd266bda7e64c149e8f5e35bb0f1ee5&oauth_version=1.0&siteAccountId=10031675&oauth_signature=2Th/wXj2puTL2YzMxSfpFFw9gq8=

I am fairly certain that the signature is correct, because when I have had incorrect signatures the system has reliably returned an "invalid signature" error.

I am currently using the Sandbox. Is this feature active in the Sandbox, and if so, any ideas what might be going wrong?

Solution

  • The Edit feature is not available at Sandbox environment and is only available once you have your own environment with Yodlee.
