class Conekta::Configuration

Attributes

access_token[RW]

Defines the access token (Bearer) used with OAuth2.

access_token_getter[RW]

Defines a Proc used to fetch or refresh access tokens (Bearer) used with OAuth2. Overrides the access_token if set @return [Proc]

api_key[RW]

Defines API keys used with API Key authentications.

@return [Hash] key: parameter name, value: parameter value (API key)

@example parameter name is “api_key”, API key is “xxx” (e.g. “api_key=xxx” in query string)

config.api_key['api_key'] = 'xxx'
api_key_prefix[RW]

Defines API key prefixes used with API Key authentications.

@return [Hash] key: parameter name, value: API key prefix

@example parameter name is “Authorization”, API key prefix is “Token” (e.g. “Authorization: Token xxx” in headers)

config.api_key_prefix['api_key'] = 'Token'
base_path[RW]

Defines url base path

client_side_validation[RW]

Set this to false to skip client side validation in the operation. Default to true. @return [true, false]

debugging[RW]

Set this to enable/disable debugging. When enabled (set to true), HTTP request/response details will be logged with ‘logger.debug` (see the `logger` attribute). Default to false.

@return [true, false]

force_ending_format[RW]
host[RW]

Defines url host

inject_format[RW]
logger[RW]

Defines the logger used for debugging. Default to ‘Rails.logger` (when in Rails) or logging to STDOUT.

@return [#debug]

params_encoder[RW]

Set this to customize parameters encoder of array parameter. Default to nil. Faraday uses NestedParamsEncoder when nil.

@see The params_encoder option of Faraday. Related source code: github.com/lostisland/faraday/tree/main/lib/faraday/encoders

password[RW]

Defines the password used with HTTP basic authentication.

@return [String]

proxy[RW]
Proxy setting

HTTP Proxy settings

return_binary_data[RW]

Set this to return data as binary instead of downloading a temp file. When enabled (set to true) HTTP responses with return type ‘File` will be returned as a stream of binary data. Default to false.

scheme[RW]

Defines url scheme

server_index[RW]

Define server configuration index

server_operation_index[RW]

Define server operation configuration index

server_operation_variables[RW]

Default server operation variables

server_variables[RW]

Default server variables

ssl_ca_file[RW]
TLS/SSL setting

Set this to customize the certificate file to verify the peer.

@return [String] the path to the certificate file

ssl_client_cert[RW]
TLS/SSL setting

Client certificate file (for client certificate)

ssl_client_key[RW]
TLS/SSL setting

Client private key file (for client certificate)

ssl_verify[RW]
TLS/SSL setting

Set this to false to skip verifying SSL certificate when calling API from https server. Default to true.

@note Do NOT set it to false in production code, otherwise you would face multiple types of cryptographic attacks.

@return [true, false]

ssl_verify_mode[RW]
TLS/SSL setting

Any ‘OpenSSL::SSL::` constant (see ruby-doc.org/stdlib-2.5.1/libdoc/openssl/rdoc/OpenSSL/SSL.html)

@note Do NOT set it to false in production code, otherwise you would face multiple types of cryptographic attacks.

temp_folder_path[RW]

Defines the temporary folder to store downloaded files (for API endpoints that have file response). Default to use ‘Tempfile`.

@return [String]

timeout[RW]

The time limit for HTTP request in seconds. Default to 0 (never times out).

username[RW]

Defines the username used with HTTP basic authentication.

@return [String]
