Threema on PC: threema is a Paid App, developed by the Threema GmbH for Android devices, but it can be used on PC or Laptops as well. We will look into the process of How to Download and install threema on PC running Windows 7, 8, 10 or Mac OS X. Thanks to encryption, you can chat with your friends with Threema. IOS: Threema My ID camera icon in the top right corner; If you are having trouble scanning a QR code, please make sure the camera is not too close (below 10 in/25 cm), which might prevent it from focussing. Please note: The QR code of contacts should not be confused with the QR code of ID exports and the QR code used to connect to Threema Web.
Hier finden Sie als Entwickler alle nötigen Informationen und den Source Code zur erfolgreichen Implementierung von Threema Gateway in Ihrer Umgebung.
Threema stellt kein grafisches User-Interface für den Threema Gateway zur Verfügung. Das Message API ist eine Schnittstelle, die aus kundenspezifischer Software heraus angesprochen werden kann, um Nachrichten via Threema Gateway zu versenden und zu empfangen.
Threema also offers encrypted chats for work on a separate network, but there’s no video calling. Video calls are a must for any workplace. Check out these video calling apps and their use cases and take your video calls to the next level! Threema pricing: $2.99. Available on: Android, iOS, Windows Phone, Web. Any chat app team has a chance to grab the brass ring by bridging the gap between phone, tablet, and PC/Mac - it shouldn't matter what device I use. But it seems that the phone app teams are universally myopic. Sigh and the search goes on. Use your Android phone's camera as a wireless webcam in PC or Mac. Install needed drivers and use your phone with Skype, MSN Messenger etc video applications. It supports resolutions up to 4K.
This API can be used to send messages to any Threema user, and to receive incoming messages and delivery receipts. There are two main modes of operation:
![]()
The mode that you can use depends on the way your account was set up.
To make client-side integration as simple as possible, the API is based on plain old HTTPS GET/POST operations. Authentication details (i.e. the API identity and key) are passed as GET/POST parameters as well (no need for HTTP authentication). The HTTP status code reflects the result of the operation (e.g. 200 OK, 401 Unauthorized, 402 Payment Required, 404 Not Found etc.).

Bulk lookup
URL: https://msgapi.threema.ch/lookup/bulk?from=
xxxxxxxx &secret=xxxxxxxx
This URL can be used to lookup up to 1000 phone number hashes or email address hashes per request. See above for details on the hashing.
The API identity and secret must be passed in the URL query string for authentication (use URL encoding).
The POST request body must be a JSON document with the following format:
The response will also be returned as a JSON document:
In this example, matches were found for one phone number hash and one email address hash, while no matches were found for the other hashes. Note: if both a phone number hash and an email address hash are provided that resolve to the same identity, only one entry will be returned in the response array, but it will have both a phoneHash and an emailHash key. At most 1000 hashes may be specified per request (i.e. the number of phone number hashes plus the number of email hashes may not be more than 1000). Slideshow app for mac google photos.

Check file reception capability of an ID
Before you send a file to a Threema ID using the blob upload (+ file message), you may want to check whether the recipient uses a Threema version that supports receiving files. The receiver may be using an old version, or a platform where file reception is not supported.
URL: https://msgapi.threema.ch/capabilities/XXXXXXXX?from=
xxxxxxxx &secret=xxxxxxxx
The API identity and secret must be passed in the corresponding GET parameters for authentication (use URL encoding).
The result is a text/plain response of supported capabilities, separated by commas. Currently defined capabilities:
More capabilities may be added in the future (separated with commas), so you should match on substrings when checking for
file . Gif player for mac. The order in which the capabilities are returned is not defined.
Example result:
text,image,video,audio,file
Possible HTTP result codes:
Key Lookups
For the end-to-end encrypted mode, you need the public key of the recipient in order to encrypt a message. While it's best to obtain this directly from the recipient (extract it from the QR code), this may not be convenient, and therefore you can also look up the key associated with a given ID from the server.
URL: https://msgapi.threema.ch/pubkeys/XXXXXXXX?from=
xxxxxxxx &secret=xxxxxxxx
The API identity and secret must be passed in the corresponding GET parameters for authentication (use URL encoding).
The public key corresponding to the ID will be returned as a text/plain response (hex encoded).
Possible HTTP result codes:
It is strongly recommended that you cache the public keys to avoid querying the API for each message.
Threema WebIncoming Messages and Delivery Receipts
If your account is operating in end-to-end encrypted mode and incoming messages have been enabled on it, you can specify an HTTPS URL callback that will be called whenever an incoming message or delivery receipt arrives for your API identity. You can set or change the callback URL in the Threema Gateway administration panel.
Callback parameters
Your callback URL will be called with the following POST parameters (application/x-www-form-urlencoded):
Note that the message first needs to be decrypted before it can be determined whether it is an incoming text/media message or a delivery receipt.
MAC calculation
For each callback, the server includes a || denotes concatenation. The parameters are concatenated in the same form as they were included in the POST (i.e. including any hex encoding, but not including any URL encoding). The secret that is used for the HMAC operation is the API authentication secret.
mac parameter than can be used to verify the authenticity of the call and the included information. This parameter is calculated as follows:
It is recommended that receivers verify the
mac parameter before attempting to parse the other parameters and decrypt the message.
Callback results and retry
If the connection to your callback URL fails or your callback does not return an HTTP 200 status, the API will retry 3 more times in intervals of 5 minutes. If all attempts fail, the message is discarded.
Certificates and cipher suites
The server that hosts the callback URL must use a valid and trusted SSL/TLS certificate (not self-signed). If in doubt, please contact customer service and specify the issuing CA of your certificate.
File Upload and DownloadUpload
URL: https://msgapi.threema.ch/upload_blob
POST parameters (multipart/form-data):
URL parameters ('GET'):
Please note that the authentication parameters must be passed in the request URL (
'/upload_blob?from=.&secret=.' ), while the actual blob data needs to be sent as a multipart/form-data parameter. Infamous second son beta key generator.
Possible HTTP result codes:
The ID of the new blob is returned as text/plain. One credit is deducted for the upload of a blob.

URL: https://msgapi.threema.ch/blobs/blobId
GET parameters:
Possible HTTP result codes:
Please note: after a blob download has first been attempted, the blob may be deleted from the server within an hour.
Querying Account InformationGet remaining credits
URL: https://msgapi.threema.ch/credits?from=
xxxxxxxx &secret=xxxxxxxx
The API identity and secret must be passed in the corresponding GET parameters for authentication (use URL encoding).
The number of credits left on the account that the given ID belongs to will be returned as a text/plain response. Note: several IDs may use the same account, and thus share the same credit balance.
Possible HTTP result codes:
E2E Message Format
The end-to-end encrypted messages use the following binary format:
Type
The first byte denotes the message type:
Data
The message data.
Padding
A random amount of PKCS#7 style padding (between 1 and 255 bytes, inclusive) is appended to each message. The padding consists of the random number n repeated n times.
Example paddings:
To add padding (pseudocode):
To remove padding (pseudocode):
Example
The text message 'hello threema' with 7 bytes of padding would look like this before encryption / after decryption:
Threema is trusted by millions and known for its unparalleled security and privacy protection. No other messenger offers a similar level of security, metadata restraint, and confidentiality.
Details about the encryption, key-pair management, physical data security, data protection laws, and other security advantages of our decentralized architecture are summarized in the Security and Privacy Reference Sheet.
