A globally unique identifier or GUID (pronounced /??u??d/ or /??w?d/) is a unique reference number used as an identifier in computer software So a Document ID looks like this:
3F2504E0-4F89-11D3-9A0C-0305E82C3301 Except for some reason the one that shows in My Mimeo is missing the dashes, and doesn't work when you pass through the API.
So I ask my API developer, where is the easiest place to get the Document ID? He says, "In the URL or as property of document". I explain it doesn't work without dashes. His response is, Developers will understand, and know to put dashes back in. And that is a hazard of putting developers as the public face of your API. They make a lot of assumptions based upon what they know. API Evangelists and developer advocates should definitely have programming skills, but ideally they should have a balance of proramming, business and marketing skills.
