API services such as Google Vision and Monkey Learn require credentials for access. The exact credentials depends on each service. Usually this entails registering for an account, and acquiring a key or authorization token. The credentials are not included in this repository as doing so presents a security risk. Instructions for each service follow below. Please check the documentation for the relevant service for more details.
- Follow the instructions for "Setup an API key" here: https://cloud.google.com/natural-language/docs/common/auth. Note: The API key should not be restricted.
- In the XCode project, copy or rename "google-api-config.default.plist" to "google-api-config.plist".
- Edit the file from step 2, and enter the Google API key for the "key" field.
- Login to MonkeyLearn here: http://monkeylearn.com/
- Find the API Token under the "API Keys" section under "My Account". https://app.monkeylearn.com/main/my-account/tab/api-keys/
- In the XCode project, copy or rename "monkeylearn-api-config.default.plist" to "monkeylearn-api-config.plist".
- Edit the plist file from step 3, and enter the API token for the "authorizationToken" field.
