You can create integrations with trading partners that require an AS2 connection. Find out more about what AS2 is and how it works with integrator.io.
Before you can establish your connection, you and your partner must exchange certain pieces of info. Find out more about this info is and how it works.
The following items should have already been determined and shared with your partner:
-
The X.509 Certificate that contains info that you need, like the ID and public key.
-
The certificate’s private key
-
Your unique ID
-
MDN signing algorithm
-
Decryption algorithm
-
Signature verification algorithm
-
AS2 URL
-
AS2 ID
-
Asynchronous URL, which is necessary only if your partner requires an async MDN
-
MDN verification algorithm, used by integrator.io to verify MDNs from your partner
-
Encryption algorithm for sending messages to your partner
-
Signing algorithm for sending messages to your partner
-
Public key
Important
To avoid the CERT_HAS_EXPIRED error in integrator.io:
-
Ensure that you renew the X.509 certificate and the X.509 private key before it expires, share the X.509 certificate with the trading partner, and ensure this information is updated in the trading partner's AS2 connection
-
Ensure that the trading partner renews their X.509 certificate and X.509 private key before it expires, ensure that the trading partner's X.509 certificate is shared with you, and update this certificate in your AS2 connection
-
From the Tools menu, navigate to Flow Builder .

Immediately, you’re asked to create or select a Connection before continuing. Click the + icon to start defining your new connection.
Name (required): Enter a unique name to the connection for easy reference.
AS2 URL (required): Select the URL to which your trading partners will send AS2 documents. These URLs are shared by all integrator.io accounts. Select the https protocol if your software has an HTTPS/SSL CA certificate, provided by Amazon Trust Services Repository.
AS2identifier (required):Create an ID that’s unique to your integrator.io account. You should have one ID for production and one for sandbox, if needed.
Require MDNs from partners (required, disabled): This field is always set to Yes because integ rator.io requires MDNs. Find out more about MDNs and how they work to keep your data secure.
Require asynchronous MDNs (required, disabled): This field is always set to No because integrator.io requires synchronous MDNs.
MDN signing (required): C hoose your signature type from the list of standard algorithms.
MDN encoding (optional): Choose Base64 or Binary.
Decryption algorithm (required): Choose your decryption algorithm from the list of standard algorithms.
Signature verification algorithm (required): C hoose from the list of standard algorithms for integrator.io to use to verify messages from your partner.
Incoming message encoding (required): C hoose the character encoding of the incoming HTTP message body in case it’s encrypted (Base64 or Binary , with Base64 being the default).
X.509 certificate (required): Paste the certificate with which the message will be signed. Your partner will verify the signature. This certificate must be in PEM format. If it is not, you can convert it in OpenSSL.
X.509 private key (required): Paste your private key. We will use this key to decrypt the messages from your partners. This key also must be in PEM format.
AS2 IP addresses (informational): If your partner’s server is behind a firewall, provide your partner with these addresses for their firewall whitelist.
In the AS2 connection form, under Partner AS2 station configuration, fill in the necessary fields with your partner’s info.
Partner’s AS2 URL (required): Enter the URL for establishing an AS2 connection with your partner.
Partner’s AS2 identifier (required): Enter your partner’s unique ID.
Partner requires asynchronous MDNs (optional): Check this box if your partner wants the MDN to be sent separately from the HTTP response.
-
Partner’s URL for asynchronous MDNs (required when Partner requires asynchronous MDNs is selected): Provide the digest algorithm for integrator.io to use when verifying the MDN returned by your trading partner.
MDN signature verification (optional): Check this box if your trading partner requires that the MDN signature be verified. Otherwise, integrator.io will not attempt to verify the signature.
-
MDN verification algorithm (optional, enabled when MDN signature verification is selected): Choose the digest algorithm for integrator.io to use when verifying the MDN returned by your trading partner.
Encryption type (required): Choose the algorithm you want integrator.io to use to encrypt messages sent to your partners. Your partner should have shared this preference with you already.
Signing (required):Choose from the list of standard algorithms.
Encoding (optional): Select the character encoding used by integrator.io for outgoing messages when they are encrypted (Base64 or Binary , with Base64 being the default).
Signature encoding (optional): Choose the way your partner expects the signature to be encoded on the receiving side ( Base64 or Binary ) . This setting applies only when Encryption type is blank or set to None.
Partner’s certificate (required): Paste your partner’s public certificate.
In the AS2 connection form, choose from the three HTTP authentication types:
If you choose None, you may proceed to configure the API rate limits.
Basic authentication means that the connection prompts for only a username and password.
Authentication type (required): Choose Basic.
Authentication fail status code (optional): If the service you want to connect to returns authentication errors other than 401, enter the code that indicates that the authentication failed.
Authentication fail path (optional): If the service you want to connect to puts the authentication error in the HTTP body, enter the path to the error.
Authentication fail values (optional): If you supplied a fail path above, enter the fail condition values to test to try to figure out why the connection failed.
Username (required): Enter your username.
Password (required): Enter your password.
Configure API rate limits (optional): Check this box to expand the rate limit options.
This method uses a token issued to you by your partner to establish your AS2 connection.
Authentication type (required): Choose Token.
Authentication fail status code (optional): If the service you want to connect to returns authentication errors other than 401, enter the code that indicates that the authentication failed.
Authentication fail path (optional): If the service you want to connect to puts the authentication error in the HTTP body, enter the path to the error.
Authentication fail values (optional): If you supplied a fail path above, enter the fail condition values to test to try to figure out why the connection failed.
Token (required): Enter the token you got from your partner. Multiple layers of protection are in place, including AES 256 encryption, to keep your token secure. When editing this form later, you must enter this token again; it is stored only for a saved connection.
Location (optional): You can decide where to put the token:
-
Header: Set the token as a request header
-
URL parameter: Add the token to the URL in a parameter
-
Body: Embed the token in the request body
Location (optional): Choose Header.
Header name (optional): Enter a custom header name, if the AS2 system requires something other than the default, Authorization.
Scheme (optional): Choose the HTTP authentication scheme you want to use. By default, integrator.io will follow HTTP specs with regards to auth scheme names (such as Bearer, OAuth, and MAC), but if the API you are connecting to does not follow the specs exactly, this field provides an override.
Configure token refresh (optional): Check this box to expand the token refresh options.
Configure API rate limits (optional): Check this box to expand the rate limit options.
Location (optional): Choose URL parameter.
Parameter name (optional): Enter the name of parameter that contains the token. For example, if you enter myAS2ConnectionToken , then all HTTP requests will include: ?myAS2ConnectionToken=[token].
Configure token refresh (optional): Check this box to expand the token refresh options.
Configure API rate limits (optional): Check this box to expand the rate limit options.
If you are sending the token in the request, no further information is needed. The provided token will appear in the body of your request.
Configure token refresh (optional): Check this box to expand the token refresh options.
Configure API rate limits (optional): Check this box to expand the rate limit options.
If your token expires after a certain amount of time, describe how to refresh it. Your partner will provide you will all of the info necessary for refreshing your token.
