Validate a Mapbox Tiling Service recipe
Arguments
- recipe
A recipe list, created with
mts_make_recipe()- access_token
Your Mapbox access token.
Value
A response from the API indicating whether the MTS recipe is valid or not. If the recipe is valid, returns TRUE, allowing you to use the output of this function for error handling pipelines. If the recipe is invalid, the function returns FALSE and prints the API response telling you why the recipe is invalid.
