Use the Springboard API to customize you own document templates
The basic process for editing your Springboard label (and other) templates is as follows:
You can get a list of all templates available with GET /api/templates
Once you have found the template you would like to modify, you can retrieve the data with GET /api/templates/<template_id> where <template_id> is the ID of the template you would like to modify. That will return JSON that will have a key called content that contains the code for the template.
While modifying the template, you will access the fields available in a similar fashion as our Ruby client. For instance when modifying a label template, you would access the items price with item['price'] whereas if you had a custom field called category that you would like displayed on your label it would be called item['custom']['category'].
After you have finished making your modifications, you can push the modified template code back to us with PUT /api/templates/#{{template_id}} with the request body {"content”:<new_content>} where <new_content> is the modified template code.
