Zoho Creator: Public URL of an Image field / Upload to Shopify API

Zoho Creator: Public URL of an Image field / Upload to Shopify API

Category: Zoho
Hits: 45136
What?
This is an article to document how I downloaded an image held in a Zoho Creator form, and sent it to an API wanting the publicly accessible link or URL of the image.

Why?
I've got some other articles on handling images in Zoho Creator (see "Sources" below), the most relevant one being my article Zoho Deluge: Get Image Uploaded in Creator Form which has one method of getting a public link.

My use-case scenario here is that while I could upload the link from Creator to eBay's Picture Services successfully, Shopify would not accept any links I gave it. Why not use the links that eBay returns? Well eBay returns URLs to images that have been resized to 400x400 (even with tweak to return 800x800). I wanted a way to upload my image directly to Shopify in 3024x3024 resolution (or the size that the client wants: iPhone res). I then found that Shopify does accept a Base64Encoded version of the image and the below is how I achieved this.

How?
First-off, let me list the various formats that Zoho Creator says that public link exists. Let's say I have a field called Main_Photo and this is in a form called Portal_Listing with a report/view called Portal_Listing_Report and I have a publish key held in v_ListingPublishKey and lastly, my datacenter is .COM:

URL Syntax #1
copyraw 
// works in eBay
v_ImageSrc = "https://creator.zoho.com/file" + zoho.appuri + "Portal_Listing_Report/" + input.ID + "/Main_Photo/image-download/" + v_ListingPublishKey + "?filepath=/" + v_Filename;
  1.  // works in eBay 
  2.  v_ImageSrc = "https://creator.zoho.com/file" + zoho.appuri + "Portal_Listing_Report/" + input.ID + "/Main_Photo/image-download/" + v_ListingPublishKey + "?filepath=/" + v_Filename; 

URL Syntax #2
copyraw 
// works in eBay
v_ImageSrc = "https://creator.zohopublic.com" + zoho.appuri + "Portal_Listing_Report/" + input.ID + "/Main_Photo/image-download/" + v_ListingPublishKey + "/" + v_Filename;
  1.  // works in eBay 
  2.  v_ImageSrc = "https://creator.zohopublic.com" + zoho.appuri + "Portal_Listing_Report/" + input.ID + "/Main_Photo/image-download/" + v_ListingPublishKey + "/" + v_Filename; 

URL Syntax #3
copyraw 
// Works in eBay
v_ImageSrc = "https://creatorexport.zoho.com" + zoho.appuri + "Portal_Listing_Report/" + input.ID + "/Main_Photo/image-download/" + v_ListingPublishKey + "/" + v_Filename;
  1.  // Works in eBay 
  2.  v_ImageSrc = "https://creatorexport.zoho.com" + zoho.appuri + "Portal_Listing_Report/" + input.ID + "/Main_Photo/image-download/" + v_ListingPublishKey + "/" + v_Filename; 

URL Syntax #4
The following won't work for the example below as it doesn't have the publish/public key, but it can be used internally:
copyraw 
// DOESN'T WORK FOR ME!!!
v_ImageSrc = "https://creatorexport.zoho.com/DownloadFile.do?filepath=/"+v_Filename+"&sharedBy="+zoho.adminuser+"&appLinkName="+zoho.appname+"&viewLinkName=Portal_Listing_Report";
  1.  // DOESN'T WORK FOR ME!!! 
  2.  v_ImageSrc = "https://creatorexport.zoho.com/DownloadFile.do?filepath=/"+v_Filename+"&sharedBy="+zoho.adminuser+"&appLinkName="+zoho.appname+"&viewLinkName=Portal_Listing_Report"; 

URL Syntax #5 [image]: Update 2023
Again this example doesn't include the publish key but can be used across apps in Creator [note this is just for quick ref]. Where my form is called "My_Form" and the image field is "My_Photo" [also note: instead of zoho.appuri, we are hardcoding the appowner and appname as this is used across Creator apps, ie. images are stored in a separate app]:
copyraw 
l_CompatiblePhotoExtensions = {"png","jpg","jpeg","gif","bmp","heic"};
c_Document = My_Form[ID == 1234567890];
//
// for image field type
v_PhotoFull = ifnull(c_Document.My_Photo,"");
v_PhotoWithExt = v_PhotoFull.getSuffix("/image/").getPrefix("\"");
v_PhotoFileExtension = v_PhotoWithExt.subString(v_PhotoWithExt.lastIndexOf(".") + 1).toLowerCase();
//
if(l_CompatiblePhotoExtensions.containsIgnoreCase(v_PhotoFileExtension))
{
	v_ThisPhotoSrc = "https://creator.zoho.com/file/appowner/appname/My_Form_Report/" + c_Document.ID + "/My_Photo/image-download?filepath=/" + v_PhotoWithExt;
}
  1.  l_CompatiblePhotoExtensions = {"png","jpg","jpeg","gif","bmp","heic"}; 
  2.  c_Document = My_Form[ID == 1234567890]; 
  3.  // 
  4.  // for image field type 
  5.  v_PhotoFull = ifnull(c_Document.My_Photo,""); 
  6.  v_PhotoWithExt = v_PhotoFull.getSuffix("/image/").getPrefix("\""); 
  7.  v_PhotoFileExtension = v_PhotoWithExt.subString(v_PhotoWithExt.lastIndexOf(".") + 1).toLowerCase(); 
  8.  // 
  9.  if(l_CompatiblePhotoExtensions.containsIgnoreCase(v_PhotoFileExtension)) 
  10.  { 
  11.      v_ThisPhotoSrc = "https://creator.zoho.com/file/appowner/appname/My_Form_Report/" + c_Document.ID + "/My_Photo/image-download?filepath=/" + v_PhotoWithExt; 
  12.  } 

URL Syntax #6 [file]: Update 2023
Same again but this is for a field of type document/file rather than image. Where my form is called "My_Form" and the file upload field is "My_File":
copyraw 
c_Document = My_Form[ID == 1234567890];
//
// for file upload field type
v_DocFileName = ifnull(c_Document.My_File,"");
v_DocExtension = v_DocFileName.subString(v_DocFileName.lastIndexOf(".") + 1).toLowerCase();
v_ThisDocSrc = "https://creator.zoho.com/file/appowner/appname/My_Form_Report/" + c_Document.ID + "/My_File/download?filepath=/" + v_DocFileName;
//
// with public key
v_PublishKey = "1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
v_ThisDocSrc = "https://creator.zoho.com/file/appowner/appname/My_Form_Report/" + c_Document.ID + "/My_File/download/" + v_PublishKey + "?filepath=/" + v_DocFileName;
//
// if My_File is in a subform
v_DocFileName = ifnull(row.My_File,"");
v_ThisDocSrc = "https://creator.zoho.com/file/appowner/appname/My_Form_Report/" + c_Document.ID + "/My_Subform.My_File/download?filepath=/" + v_DocFileName;
  1.  c_Document = My_Form[ID == 1234567890]; 
  2.  // 
  3.  // for file upload field type 
  4.  v_DocFileName = ifnull(c_Document.My_File,""); 
  5.  v_DocExtension = v_DocFileName.subString(v_DocFileName.lastIndexOf(".") + 1).toLowerCase(); 
  6.  v_ThisDocSrc = "https://creator.zoho.com/file/appowner/appname/My_Form_Report/" + c_Document.ID + "/My_File/download?filepath=/" + v_DocFileName; 
  7.  // 
  8.  // with public key 
  9.  v_PublishKey = "1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"; 
  10.  v_ThisDocSrc = "https://creator.zoho.com/file/appowner/appname/My_Form_Report/" + c_Document.ID + "/My_File/download/" + v_PublishKey + "?filepath=/" + v_DocFileName; 
  11.  // 
  12.  // if My_File is in a subform 
  13.  v_DocFileName = ifnull(row.My_File,""); 
  14.  v_ThisDocSrc = "https://creator.zoho.com/file/appowner/appname/My_Form_Report/" + c_Document.ID + "/My_Subform.My_File/download?filepath=/" + v_DocFileName; 

The API Solution
The following solution requires that your target API accepts base64encoded images or that you can send these in a cURL request (same thing really):
copyraw 
string API.fn_ShopifyQuery_UploadPhoto(int p_Position, int p_ProductID)
{
	v_Output = "";
	m_Header = Map();
	m_Header.put("Content-Type","application/json");
	// 
	// your shopify details 
	v_ClientID = "<YOUR_CLIENT_ID>"; 
	v_ClientSecret = "<YOUR_CLIENT_SECRET>"; 
	v_ShopID = "example.myshopify.com"; 
	v_ShopifyURL = "https://" + v_ClientID + ":" + v_ClientSecret + "@" + v_ShopID; 
	v_ShopifyApiVersion = "2020-01"; 
	//
	// your creator details
	v_ListingPublishKey = "AAAAABBBBBCCCCDDDDEEEFFFGGGGHHHIIIJJJKKLLLMMMNNOOOPPPQQWRRRSSTTUUVVWWXXYYZZ122345567890"; 
	v_Position = ifnull(p_Position, 1);
	v_ShopifyProductID = ifnull(p_ProductID, 123456789012);
	r_PortalListing = Portal_Listing[Shopify_Product_ID == v_ShopifyProductID];
	if(r_PortalListing.count()>0)
	{
		v_Filename = r_PortalListing.Main_Photo.getSuffix("/image/").getPrefix("\"");
		v_ImageSrc = "https://creator.zoho.com/file" + zoho.appuri + "Portal_Listing_Report/";
		v_ImageSrc = v_ImageSrc + r_PortalListing.ID + "/Main_Photo/image-download/" + v_ListingPublishKey;
		v_ImageSrc = v_ImageSrc + "?filepath=/" + v_Filename;
		r_DownloadPhoto = invokeUrl
        [
        	url: v_ImageSrc
        	type: GET
        ];
		r_DownloadPhoto.setParamName("file");
		v_EncodedImg = zoho.encryption.base64Encode(r_DownloadPhoto);
		m_Params = Map();
		m_SubParams = Map();
		m_SubParams.put("position", 1);
		m_SubParams.put("attachment", v_EncodedImg);
		m_SubParams.put("filename", v_Filename);
		m_Params.put("image", m_SubParams);
		//
		v_Endpoint = v_ShopifyURL + "/admin/api/" + v_ShopifyApiVersion.toString() + "/products/" + v_ShopifyProductID + "/images.json";

Sends something like the following request (sent using Zoho Deluge but the cURL breakdown as follows):
copyraw 
curl -d '{"image":{"position":1,"attachment":"/9/R0lGODlhbgCMAPf ... ... ... Q7PCAAOw==\n","filename":"my_test_photo.jpg"}}'
-X POST "https://your-development-store.myshopify.com/admin/api/2021-10/products/9876543210987/images.json" \

Correction / Additional
The above solution means that for every photo uploaded, an API call is used up. If you have low limits, even 2000, this means you can only upload 100 products a day if they each have 20 photos (even less products then that as the upload of a product costs 1 API call). But I have found you can submit all photos in one go as well:
copyraw 
// build up list of photos from Creator fields
l_CreatorPhotos = List();
v_ListingPublishKey = "AAAAABBBBBCCCCDDDDEEEFFFGGGGHHHIIIJJJKKLLLMMMNNOOOPPPQQWRRRSSTTUUVVWWXXYYZZ122345567890";
if(!isnull(input.Main_Photo))
{
	v_Filename = input.Main_Photo.getSuffix("/image/").getPrefix("\"");
	v_ImageSrc = "https://creator.zoho.com/file" + zoho.appuri + "Portal_Listing_Report/";
	v_ImageSrc = v_ImageSrc + input.ID + "/Main_Photo/image-download/" + v_ListingPublishKey;
	v_ImageSrc = v_ImageSrc + "?filepath=/" + v_Filename;
	l_CreatorPhotos.add(v_ImageSrc);
}
//
// then upload
l_ShopifyUploadImages = List();
v_PositionIndex = 0;
for each  v_CreatorImageSrc in l_CreatorPhotos
{
    if(v_CreatorImageSrc != "")

Correction / Additional version 2.0
Playing around with this for a client, I found an even better solution! When creating or updating a product, you can instead of giving it Image URLs, give it the Image as attachment a base64 encoded string. Note the above says that 10 photos produced 10 webhooks but actually I'd overlooked the webhook used to invokeUrl download a Creator file so it was using 20 webhooks; the following reduces that back down to 10 webhooks (1 to download each photo and base64 encode it but no extras to upload it in addition to the product update):
copyraw 
// initialize
m_Product = Map();
b_CreateProduct = true;  
//
// I have a field called Shopify Product ID which stores the... um... shopify product id...
if(!isNull(input.Shopify_Product_ID))
{
    m_Product.put("id",input.Shopify_Product_ID);
    b_CreateProduct = false;
}
//
// title and HTML
m_Product.put("title",input.Listing_Title);
if(!isNull(input.Full_Shopify_HTML_Code))
{
    m_Product.put("body_html",input.Full_Shopify_HTML_Code);
}
m_Product.put("vendor",input.Brand);
m_Product.put("product_type",input.Item_Type);
//
// listings / channels
m_Product.put("published_scope","global");
m_Product.put("published",true);  // set to true when comfortable with it publishing correctly
m_Product.put("status",ifnull(input.Publish_Status.toLowerCase(),"draft"));
//
// build up variant list under this product
l_Variants = List();
m_Variant = Map();
m_Variant.put("weight",0.0);
m_Variant.put("title",input.Listing_Title);
m_Variant.put("sku",input.Product_SKU);
